Abstract:
A liquid crystal light valve comprising:a plurality of light-reflecting films with one or more spaces therebetween; a semiconductor substrate connected electrically to the light-reflecting films; a counter substrate provided on an incident-light side thereof; liquid crystal disposed in a cell gap formed between the light-reflecting films and the counter substrate; counter electrodes provided on the counter-substrate; an electric circuit formed in the semiconductor substrate, which is configured to apply voltage to the light-reflecting films and the counter electrodes formed on the counter substrate; a light-blocking layer formed below the light-reflecting films; a first insulating layer formed between the light-blocking layer and the electric circuit; a second insulating layer formed between the light-reflecting films and the light-blocking layer; a stud which is configured to electrically connect the electric circuit and the light-reflecting films; light shields provided on the light-blocking layer formed below the light-reflecting films; and a third insulating layer formed between the light shields and the light-reflecting films; wherein at least one of said light shields and said light-blocking layer is configured to block the incident light from the electric circuit.
