A display device includes a lens array unit, a display unit which is configured such that a first substrate is attached to a second substrate that is disposed between the first substrate and the lens array unit, the display unit having a display area composed of matrix-arrayed pixels, a gap control layer which forms a predetermined gap between the display unit and the lens array unit, and a support member which fixes the display unit and the lens array unit on an outside of the display area of the display unit.

Display device

A liquid crystal display device has a gradation display function of at least an n-number of gray levels and has a viewing angle characteristic of Mi/Mj&#x2266;1.3 in a case where a display luminance range in a normal direction to a display surface in a gradation range of predetermined gray levels i to j is Li to Lj and a display luminance range in an oblique viewing-angle direction of 30&#xb0; or more is Mi to Mj (where n, i and j are real numbers, and n&#x2267;i&#x3e;j&#x2267;0). The liquid crystal display device has a display mode in which a display image is displayed with a display luminance range of the display image being limited to Li to Lj.

Liquid crystal display device

An LCD device includes a transparent glass plateand thin film transistor electrodesformed on the glass plate. A photosensitive insulation filmis coated on the glass plateand the thin film transistor electrodes. The insulation filmincludes transparent and reflective regionsandwhich are different in thickness. Light shielding filmsare positioned underneath boundaries of the transparent and reflective regionsand. Where an optical exposure stage includes different reflection coefficient portions, the light shielding filmsprevent light reflected by the exposure stage from reaching the insulation film thereby maintaining the accuracy of its patterning.

Liquid crystal display device and method of manufacturing the same

A first signal line and a second signal line are paired, and in one signal line selection period, CPU of the inspection circuit controls a write circuit and writes analog signals into the first signal line selected by means of a switch of the selection circuit. In the next signal line selection period, CPU controls a read circuit and reads output signals from the second signal line selected by means of the switch. CPU detects a short circuit between the paired signal lines based upon the output signals from the second signal line.

Electronic inspection of an array

There is provided a liquid crystal display wherein a first display region corresponding to a first area on which first pixel electrodes are provided displays an image by light reflection mode, and a second display region corresponding to a second area on which second pixel electrodes are provided can display an image by light transmission mode.

Liquid crystal display with display regions of light reflection mode and light transmission mode

A liquid crystal display device comprises an array substrate including a plurality of pixel electrodes, a counter substrate including a counter electrode facing the pixel electrodes, and a liquid crystal layer which modulates reflected and transmitted light of each pixel held between the substrates and defined by a corresponding pixel electrode. In particular, each pixel electrode has a conductive light reflective layer which reflects incident light and at least one opening which is formed as a missing portion of the conductive light reflective film to transmit incident light.
