In forming of an element substrate of an electro-optical device, after a plurality of films having a film that forms the pixel switching elements on one surface side of the substrate and a film that forms the pixel electrodes are formed, the substrate is removed through polishing and etching, and thus a layered structure is acquired.

An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. The directional backlight may be arranged to switch between at least a first wide angular luminance profile mode and a second narrow angular luminance profile mode. The directional backlight is arranged to illuminate an LCD with a bias electrode arranged to switch liquid crystal directors in black state pixels between a first wide angular contrast profile mode and a second narrow angular contrast profile mode. Performance of privacy operation for off-axis snoopers is enhanced in comparison to displays with only directional backlights or switchable contrast properties.

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.
