摘要： A reflective liquid crystal display device and a liquid crystal display unit capable of achieving high moisture resistance and securing long-term reliability through specifically preventing electrode corrosion in a surface portion of a pixel electrode substrate are provided. A seal portion bonds a pixel electrode substrate and a transparent electrode substrate together with a predetermined spacing in between. In this case, the pixel electrodes and a metal film are formed inside an outer surface of the seal portion on the pixel electrode substrate. Thereby, the pixel electrodes and the metal film are not exposed to air, and the moisture resistance can be secured, and electrode corrosion can be prevented. Moreover, as an adhesive surface of the seal portion is a substrate surface, compared to the case where peripheral end sources of the whole device are coated, sufficient adhesion can be secured for a long term.

摘要： An image displaying apparatus and method is provided which can provide a satisfactory display with a gradation of intensity even with a spatial light modulator which provides a binary light modulation. A light from a light source 1 is modulated by a spatial light modulator 3 which modulates a light at each pixel thereof correspondingly to a pixel data of an image to be displayed. When the pixel state of the spatial light modulator 3 is being changed, the light source 1 is turned off. When the pixel state of the spatial light modulator 3 is steady, a light pulse is irradiated from the light source 1 to the spatial light modulator 3 to display the image.
