Abstract
A reflective and transflective liquid crystal display, a figure of bump structure is defined at a pixel electrode, and a reflective layer is formed around the peripheral at the top or bottom of the figure of bump structure to define the reflective zone and the transmissive zone of each single pixel. The upper electrode can contain the figure of slit or bump structure. By adjusting the relative positions of the figures of slit or bump structure between electrodes, the pre-tilt angles and tilting directions of liquid crystal molecules can be controlled, and a multi-domain division alignment is formed, and thus a multi-domain division, semi-transmissive, and wide view angle liquid crystal panel can be formed.
Claims12
A reflective and transflective liquid crystal display and a structure of each pixel comprising:
- a first substrate which has a pixel electrode with a bump structure at its top on the surface of the first substrate;
- a reflective layer which is placed around the peripheral of a bump structure and covers part of the pixel electrode;
- a polarizing layer which covers the reflective layer and the pixel electrode;
- a first alignment film which covers the polarizing layer;
- a second substrate which has an upper electrode placed on the surface of it facing the first substrate;
- a second alignment film which covers the upper electrode;
- and
- a liquid crystal cell which is installed between the first alignment film and the second alignment film.
