LCD device including a reflection film having a convex-concave surface
View Patent ↗An LCD device includes a reflective area in each pixel. A reflection film having a convex-concave surface is provided in the reflective area, film in cross section configuration is formed. Each pixel includes a pixel electrode and a common electrode for applying a lateral electric field on a LC layer. The inclination angle of the reflection film has an inclination angle distribution, wherein the angle component in an area corresponding to the electrodes has a lower angle distribution than the angle components in an area corresponding to a gap between adjacent two of the electrodes.
1. A liquid crystal display (LCD) device comprising:
a reflection area for reflecting incident light and provided in at least a part of a pixel;
a reflection film provided in said reflection area and having a convex-concave surface; and
a plurality of electrodes for driving therebetween liquid crystal (LC) molecules in a lateral direction, wherein:
an inclination angle of said convex-concave surface has different components between a first area overlapping said electrodes and a second area overlapping a gap between adjacent two of said electrodes.
2. The LCD device according to claim 1 , wherein components of said inclination angle in said first area have a lower-angle distribution than components of said inclination angle in said second area.
3. The LCD device according to claim 1 , wherein said inclination angle of said reflection film is such that light reflected by said second area is emitted toward an observer, and light reflected by said first area is emitted toward a specular reflection direction.
4. The LCD device according to claim 1 , wherein components of said inclination angle in said second area are such that components residing in a range of 4.7 to 9.1 degrees are larger in amount than components residing in a range of 0 to 2.9 degrees, and wherein components of said inclination angle in said first area are such that components residing in a range of 0 to 2.9 degrees are larger in amount than components residing in a range of 4.7 to 9.1 degrees.
