Abstract
A liquid crystal display device can further enhance the display contrast. Reflection films are formed on pixel regions on a liquid-crystal-side surface of one substrate out of respective substrates which are arranged to face each other with liquid crystal therebetween. Light from another substrate side is incident on the reflection films through the liquid crystal and thereafter is reflected toward another substrate side. The formation of the reflection films is obviated in the vicinities of projecting portions formed in the pixel regions.
Claims9
A liquid crystal display device comprising respective substrates which are arranged to face each other in an opposed manner with liquid crystal sandwiched therebetween, and reflection films which are formed on pixel regions on a liquid-crystal-side surface of one substrate out of the respective substrates so that light from another substrate side is incident on the reflection films through the liquid crystal and thereafter is reflected toward another substrate side, wherein
- the formation of the reflection films is obviated in the vicinities of projecting portions which are formed in the pixel regions.
A liquid crystal display device comprising respective substrates which are arranged to face each other in an opposed manner with liquid crystal sandwiched therebetween, and reflection films which are formed on pixel regions on a liquid-crystal-side surface of one substrate out of the respective substrates so that light from another substrate side is incident on the reflection films through the liquid crystal and thereafter is reflected toward another substrate side, wherein
- the formation of the reflection films is obviated in peripheries of spacers which are formed in the pixel regions.
A liquid crystal display device comprising respective substrates which are arranged to face each other in an opposed manner with liquid crystal sandwiched therebetween, and reflection films which are formed on pixel regions on a liquid-crystal-side surface of one substrate out of the respective substrates so that light from another substrate side is incident on the reflection films through the liquid crystal and thereafter is reflected toward another substrate side, wherein
- the formation of the reflection films is obviated in peripheries of spacers which are formed in the pixel regions and in portions of the pixel regions except for portions which face a directing direction of rubbing on an orientation film which is brought into contact with the liquid crystal.
A liquid crystal display device comprising columnar spacers which are formed by selectively etching a material layer and an orientation film which is formed after the formation of the spacers on a liquid-crystal-side surface of one substrate out of respective substrates which are arranged to face each other in an opposed manner with liquid crystal sandwiched therebetween, wherein
- a diameter of the spacers is set to a value equal to or less than 1.55 μm and a film thickness of the orientation film is set to a value equal to or less than 20 nm.
