A highly convenient electronic device used while being worn on a body is provided. The electronic device is an arm-worn electronic device including a display panel, a power storage device, a circuit, and a sealing structure. The display panel displays an image with power supplied from the power storage device. The circuit includes an antenna and charges the power storage device wirelessly. Inside the sealing structure, the display panel, the power storage device, and the circuit are provided. The sealing structure includes a portion that transmits visible light. The sealing structure can be worn on an arm or is connected to a structure body that can be worn on an arm.

Disclosed is a display device having a QRD-based rendering structure capable of achieving the same performance as a display device using a conventional DRD scheme while performing a horizontal 2-dots inversion. Further, disclosed is a QRD-based display device with a new rendering structure to achieve a performance equivalent to that of an existing DRD scheme.

According to one embodiment, a display device includes a display panel including a plurality of pixel electrodes, a common electrode and a display function layer, a light source unit, and a controller. When a character is displayed in a first area of a display area, the controller applies a color other than the achromatic color to the first area, and makes a second area and a non-object area transparent. Transparency of the non-object area is higher than transparency of the second area.

Pixels P arranged in a matrix shape have at least two sub-pixels defined by including an electrode pair of a sub-pixel electrode and a counter electrode facing each other through a liquid crystal layer. Regarding at least two sub-pixels included in the pixel P, a voltage difference between voltages applied to the liquid crystal layer through the electrode pair, a brightness difference or a luminance difference varies depending on an arrangement position of the pixel P in a row direction and/or column direction.

A video processing device generates a display video signal to be supplied to a liquid crystal display unit that is driven by a frame inversion scheme. The video processing device includes a controller and a video signal processor. The controller controls a vertical synchronizing signal included in an interlace video signal input from outside the video processing device so that a display invalid section having a predetermined number of fields is set for the interlace video signal at a predetermined period. The video signal processor i) generates the display video signal based on the interlace video signal in which the display invalid section has been set by control of the vertical synchronizing signal and ii) outputs the display video signal to the liquid crystal display unit.

Provided is to a display element capable of displaying an image on both sides thereof. In the display element, display operation is not constantly performed on both sides, and the display operation is, as necessary, switched to displaying only on one side without lowering the efficiency of a backlight or other light emitting bodies. The structure is made such that a planar light emitting body capable of emitting light in directions of both faces is sandwiched between two light control elements capable of electrically switching, from outside, between a light reflection state and a light transmission state. In such a structure, the faces of the light control elements serving as light reflection surfaces in the light reflection state face the planar light emitting body, and the planar light emitting body and the light control elements are further sandwiched between two liquid crystal elements.

Transparency of the non-object area is higher than transparency of the second area.

A liquid crystal display apparatus comprises a planar first electrode, multiple second electrodes and third electrodes that overlap with the first electrode and are alternately arranged, in correspondence to one subpixel. The second electrode and the third electrode are independently driven. A voltage for driving the liquid crystal is individually applied between the second electrode and the first electrode and between the third electrode and the first electrode.

Pixels P arranged in a matrix shape have at least two sub-pixels defined by including an electrode pair of a sub-pixel electrode and a counter electrode facing each other through a liquid crystal layer. Regarding at least two sub-pixels included in the pixel P, a voltage difference between voltages applied to the liquid crystal layer through the electrode pair, a brightness difference or a luminance difference varies depending on an arrangement position of the pixel P in a row direction and/or column direction.
