PURPOSE: To provide a liquid crystal light valve which can be applied to a high luminance image projector and has high light-resistance. CONSTITUTION: This liquid crystal light valve is provided with oriented film layers 13a and 13b which are used for introducing perpendicular orientation to a liquid crystal and composed of only a completely inorganic material through forming them with a process comprising two stages, namely a stage for obliquely vapor-depositing an inorganic material and the other stage for subjecting the vapor-deposited inorganic material to grain growth. Therefore, with this manufacturing method, the objective light valve having higher reliability can be manufactured even at the time of subjecting it to exposure to strong readout light as compared with the conventional method using an organic agent for orientation and also, this method is effective in remarkably facilitating the application of the light valve to a high luminance image projector. |
