    摘要: An optical address section, a display section and light waveguides are provided on a substrate. The light waveguides are located between the optical address section and the display section. The optical address section includes first light emission elements, while the display section includes data electrodes, phototransistors and second light emission elements. The light emitted from the first light emission elements enters the phototransistors of the display section through the light waveguides and drives the phototransistors. In accordance with the phototransistors selected, the second light emission elements emit light upon application of a voltage of the data electrodes.

    摘要: An organic electroluminescence device is placed as a back light of a liquid crystal display panel. The organic electroluminescence device is constituted by a front electrode (#112) having transparency to visible light, a rear electrode (#113) having reflection to visible light and an organic electroluminescence layer (#114) for emitting light as a predetermined voltage is applied between the front and rear electrodes. A scatter control member (#120), located between the liquid crystal panel and the organic electroluminescence panel, passes incident light within a predetermined range without scattering and passes light outside the predetermined range with scattering. Preferably, the scatter control member is constituted by a plurality of lightguiding portions (#121) having transparency to visible light and a plurality of reflection films (#122) having a reflection property to visible light.

    摘要: A phototransistor having a non-linear light vs. conductivity characteristics and an organic electroluminescent layer are sandwiched by a pair of electrodes, a predetermined voltage is applied to the pair of electrodes, and address light is irradiated on a phototransistor to let a current flow in the phototransistor, thus causing the electroluminescent layer to emit light. It is therefore possible to drive the device to present crosstalk-free gradation display with a high contrast ratio.

    摘要: A controller stores image signals Sp represented as binary values for every unit of frame. The controller divides one frame into a plurality of sub-frames representing an image by image data of two gradation levels, in accordance with respective figures of the stored image signals Sp for one frame. The image data of two gradation levels for each of the sub-frames is written into capacitors Cp from a drain driver, for every row. When the image data is "1", a drive transistor is turned on. A common driver applies a voltage of a predetermined level for every sub-frame, to control the voltage applied between electrodes of an organic EL element. As a result, the organic EL element emit light with brightness which differs between sub-frames. Images of the sub-frames are visually synthesized, so that gradation is expressed in one frame.
