There is provided an image display device that includes a display in which a background is transparently seen from a front surface side, and has a high degree of freedom at the time of installation. A liquid crystal panel (32) for adjusting transparency/light-emission adjusts, for each pixel, a ratio between transmitted light-source light and ambient light by respectively controlling a polarization direction of a reflected polarization component of the light-source light irradiated to a reflection-type polarization plate (20) from a light guide plate (180) and a polarization direction of a transmitted polarization component of the ambient light incident to the reflection-type polarization plate (20) from a rear surface side of the display, based on transparent/light-emitting pixel information. Accordingly, when the image display device is viewed from the front surface side of the display, an image is seen for each pixel, a background is transparently seen, or the background is seen so as to be superimposed on the image. Since it is not necessary to attach the image display device to a case filled with light, the image display device is widely used without limitation of use.

A system and method of driving an electrowetting display device including a plurality of sub-pixels are presented. A sub-pixel in the plurality of sub-pixels is determined to be in an open state or a closed state and a target reflectance value is determined for the sub-pixel. For the sub-pixel in the open state, the target reflectance value is determined to be less than a first threshold value, and a reflectance value of the sub-pixel is set to either a minimum reflectance value or the first threshold value. For the sub-pixel in the closed state, the target reflectance value is determined to be less than a second threshold value, and the reflectance of the sub-pixel is set to either the minimum reflectance value or the second threshold value.

A display device with improved display quality and reduced power consumption is provided. The display device includes a gate driver, a display portion, and a selection signal output circuit.

The display element is configured to update display by the first scan signal. In the pixel circuits, one display element displays an image updated with a different update frequency from another display element.

A novel information processing device that is highly convenient is provided. The information processing device includes a selection circuit having a function of supplying image data to a reflective display element, a light-emitting element, or both of them on the basis of input position coordinate data, sensing data about the illuminance of the usage environment, and the image data. An icon with high selection frequency is displayed by both the reflective display element and the light-emitting element on the basis of icon coordinate data and the input position coordinate data, so that the icon can be displayed brightly with improved visibility.

A transflective LCD device and a method of forming the same are proposed. The transflective LCD includes a first substrate, a second substrate, a first alignment film, a second alignment film and a liquid crystal layer. The first substrate and the second substrate are divided into a transmissive area and a reflective area, in which areas of the first alignment film and the second alignment film are configured respectively by different aligning angles. The liquid crystal molecules in the liquid crystal layer corresponding to the transmissive area and the reflective area are tilted by different pretilt angles. Therefore, light going one-way through the liquid crystal layer corresponding to the transmissive area generates the same phase retardation as making a round-trip through the liquid crystal layer corresponding to the reflective area. The present invention can simplify technical difficulties, and reduce occurrences of poor rubbing and dark-state light leakage.

A display device in which an image with a wide color reproduction range and bright red can be displayed is provided.

The display device includes a display surface including a pixel having red, green, blue, and yellow sub-pixels, wherein the red sub-pixel preferably has the largest aperture area.

According to one embodiment, a display device includes a driver, a first pixel circuit disposed apart from the driver in plan view but electrically connected to the driver, a second pixel circuit separated further from the driver than the first pixel circuit in plan view but electrically connected to the driver, a first pixel electrode overlapping the driver in plan view, a second pixel electrode overlapping the first pixel circuit in plan view, a first relay line electrically connecting the first pixel circuit and the first pixel electrode to each other, and a second relay line electrically connecting the second pixel circuit and the second pixel electrode to each other.

The full-panel includes a display panel having a first region with an array of first subpixels of respective a first color, a second color, and a third color, and a second region with an array of second subpixels of respective the first color, the second color, and the third color. The array of first subpixels and the array of second subpixels are collectively configured to achieve a higher transmission rate in the first region to an accessory installed therein while keep a luminance ratio between the first subpixels unchanged from that between the second subpixels. Optionally, a number density and/or a unit subpixel area of the first subpixels of at least one color is smaller in the first region than that in the second region.
