Abstract
The present invention relates to a liquid crystal light valve comprising: a first substrate where a first polymer layer is formed thereon; a second substrate where a second polymer layer is formed thereon, the first polymer layer is opposite to the second polymer; and a liquid crystal material layer filled in between the first polymer layer and the second polymer layer, wherein the first polymer layer and the second polymer layer have a roughened surface, and the roughened surface is disposed between the first polymer layer and the liquid crystal material layer, or between the second polymer layer and the liquid crystal material layer.
Claims8
A method for preparing a liquid crystal light valve, comprising the steps of:
- (A) providing a first substrate and a second substrate, each of the first substrate and the second substrate forms a first polymer layer and a second polymer layer respectively, the first polymer layer and the second polymer layer are disposed opposite to each other, and the first polymer layer and the second polymer layer is disposed with a liquid crystal material layer;
- (B) executing to a heating process;
- and
- (C) executing to a cooling process, to make the first polymer layer and the second polymer layer form a roughened surface, and the roughened surface is disposed between the first polymer layer and the liquid crystal material layer or between the second polymer layer and the liquid crystal material layer;
- wherein in step (B), the first polymer layer and the second polymer layer dissolve in the liquid crystal material layer;
- and
- wherein in step (C), the first polymer and the second polymer dissolved in the liquid crystal material layer are separated out and attached onto the first polymer layer and the second polymer layer.
