Liquid crystal projection device having a liquid crystal display element that includes an electroluminescent element |
摘要 |
A liquid-crystal projection device includes an organic electroluminescent element that is sandwiched by an organic thin-film layer between an electrode layer that reflects light and a transparent electrode layer that transmits light, and a transparent liquid crystal panel that controls passage of light emitted from the surface of the organic electroluminescent element and also includes a half-mirror layer arranged on the side where light is output from the transparent electrode layer. Some of the incoming light is reflected through the transparent electrode layer to another electrode layer and the rest of the light is transmitted the distance between the half-mirror layer. The electrode layer is set to the optical distance of resonance of the light.
