A liquid crystal display includes a first substrate, a second substrate and a liquid crystal layer. The first substrate has a pixel electrode having many first slits and many second slits, connected to a third slit. Each first and second slit respectively stretches along a first and a second vector with a starting point in a junction with the third slit. Liquid crystal molecules near an alignment layer of the second substrate is aligned by the alignment layer to pre-tilt. Each projection of the long-axis of at least part of the pre-tilted liquid crystal molecules on the second substrate forms a third vector with a starting point at the end of the liquid crystal molecule near the alignment layer. An included angle between the first and the third vector is &#x3b8;, and an included angle between the second and the third vector is &#x3b8;. 90&#xb0;&#x3c;&#x3b8;&#x3c;160&#xb0;, and 90&#xb0;&#x3c;&#x3b8;&#x3c;160&#xb0;.

Liquid crystal display

A reflective liquid crystal display panel capable of performing data programming and/or data erasing via a polarized light is provided. The reflective liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer, a transflective film, a retarder and a polarizer. The second substrate is disposed over the first substrate. The liquid crystal layer is located between the first substrate and the second substrate and an optical aligned material is doped in the liquid crystal layer. The transflective film is disposed below the first substrate, and the transflective film allows the polarized light to pass through, so that the orientation of the optical aligned material doped liquid crystal layer can be controlled by the polarized light. The transflective film reflects external light source. The retarder is disposed between the transflective film and the first substrate. The polarizer is disposed on the second substrate.

Reflective liquid crystal display panel capable of being photo-programmed and restored by polarized lights

An electro-optical modulator includes a substrate, a first electrode over the substrate, a second electrode over the first electrode, the first electrode and second electrode being capable of providing an electric field between the first electrode and the second electrode, and a modulating structure between the first electrode and the second electrode, the modulating structure containing at least one liquid crystal cell capable of operating in one of a reflective mode and a transmissive mode under the control of the electrical field.
