| description | The invention belongs to the technical field of a liquid crystal device. In order to provide a high-resolution liquid crystal light valve and a preparation method thereof, the liquid crystal light valve provided by the adopted technical solution comprises a first glass substrate and a second glass substrate which are oppositely arranged, wherein a first transparent conducting thin film layer and a second transparent conducting thin film layer are arranged on the opposite side faces of the first glass substrate and the second glass substrate respectively; a photosensitive layer, a light-stopping layer, a medium reflector, a first alignment layer, a liquid crystal layer and a second alignment layer are further sequentially arranged between the first transparent conducting thin film layer and the second transparent conducting thin film layer; the photosensitive layer is a photosensitive layer in a nanometer structure, which is made of an a-Si:(CdTe):H composite material; the composite material comprises CdTe and a-Si:(CdTe), wherein the CdTe is 7% in content. A less amount of the CdTe is mixed into an a-Si:H thin film to form the a-Si:(CdTe):H composite material; the material is used as the photosensitive layer of the liquid crystal light valve, so that the migration rate of semiconductor materials of the photosensitive layer is improved, the response time is shortened, the resolution ratio and the light sensitivity of the liquid crystal light valve can be improved, and the response spectrum is widened. The technical solution is applicable to the existing reflection type liquid crystal light valve. |
