摘要： A liquid crystal is interposed between a first transparent substrate having first electrodes and a second transparent substrate having other electrodes. Pixel regions are formed at portions where the first electrodes and the other electrodes are opposed to each other. A semitransparent reflecting film is formed between the first transparent substrate and the first electrodes. The semitransparent reflecting film is formed with light transmission apertures in each pixel region. The semitransparent reflecting film also occupies portions corresponding to the gaps between the adjacent pixel regions. Alternatively, in addition to the light transmission apertures, the semitransparent reflecting film is formed with slits at positions corresponding to the gaps between the adjacent pixel regions. A light absorption film is formed between the first transparent substrate and the semitransparent reflecting film at positions corresponding to the slits, or the slits are charged with a light absorption film.

摘要： In a liquid crystal display device the reflection of light from a transmissive region is reduced, the contrast of images is enhanced and a display of inverted images is suppressed. The liquid crystal display device includes a first background film made of silicon nitride and a second background film made of silicon oxide over a glass substrate, and thin film transistors and light transmissive pixel portions are formed over the second background film. Each thin film transistor is constituted of a polysilicon film, a gate electrode, a drain electrode and a source electrode, while a gate insulation film, an interlayer insulation film and an organic film are formed over the pixel portion. Further, in the liquid crystal display device external light is reflected, wherein by forming the first background film thicker than the second background film, the inversion of images of a transmissive type liquid crystal panel can be suppressed.
