Incident light from the space between the light-reflecting films in a liquid crystal light valve of a liquid crystal display device, especially in a reflection-type liquid crystal light valve of a projection-type liquid crystal display device is effectively blocked. The liquid crystal light valve having a semiconductor substrate, a counter substrate, light-reflecting films, and liquid crystal comprises a light-blocking layer and light shields formed between the light-blocking layer and the light-reflecting films.
