  • Patent number: 6583580
    Abstract: An EL driving circuit which can operate at a satisfactory operation speed is disclosed. A voltage higher than the voltage for operating the EL element is input, and the input voltage is stepped down by the voltage step-down circuit (2) which is provided in each unit block (1). The stepped-down voltage is then supplied to a transistor (3) functioning as the driving element for driving the EL element. Therefore, even when the number of EL elements increases, sufficient source voltage can be supplied to each unit block.

    Abstract: 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.
