摘要： A pixel electrode for driving liquid crystal is formed on a planarization insulator film covering a thin film transistor, and a vertical alignment film without rubbing treatment is formed on the pixel electrode. An alignment control window that has electrode-free portion is formed in a common electrode, and a vertical alignment film is formed on the common electrode without rubbing treatment. The liquid crystal having negative dielectric constant anisotropy is controlled in an initial direction of the substantially normal direction without pretilt. Upon applying a voltage, the tilt of the alignment is controlled in the direction of a slanting electric field at the edge of the pixel electrode and the edge of the alignment control window, so that pixel division is performed. Since rubbing treatment is not performed, electrostatic breakdown of the thin film transistor is prevented and, because a black matrix is eliminated, aperture ratio is improved.

摘要： A vertically aligned type liquid crystal display includes a liquid crystal layer disposed between a plurality of pixel electrodes and a common electrode and containing vertically aligned liquid crystal molecules, the orientation of the liquid crystal molecules being controlled by electric field. An orientation control window is formed in the common electrode. A distance Wp between adjacent pixel electrodes and/or a width Ws of the orientation control window is selected so as to satisfy Wp≧d/2 and/or Ws≧d/2, where d is a distance (or a cell gap) between the pixel electrodes and the common electrode. Viewing angle is widened and a viewing angle characteristic is improved, and abnormal orientation or grittiness of an image is eliminated.

摘要： On a substrate, a gate electrode, a gate insulating film covering the gate electrode, a p-Si film, and an interlayer insulating film covering the p-Si film are formed. On these a drain electrode and a source electrode are formed, so as to form a thin film transistor. In addition, a smoothing insulator film covering the thin film transistor, a pixel electrode, and a vertical alignment film covering the pixel electrode are formed. The vertical alignment film is not processed with rubbing treatment, so that the liquid crystal having negative dielectric constant anisotropy is controlled in an initial direction of the substantially normal direction without pretilt. Upon applying a voltage, the tilt of the orientation is controlled in the direction of a slanting electric field at the edge of the pixel electrode, so that a pixel division is performed. Since the rubbing treatment is not performed, electrostatic breakdown of the thin film transistor is prevented.

摘要： On a TFT substrate, a TFT using a low-temperature poly silicon thin film as an active layer is formed and a plurality of pixel electrodes are formed over the TFT and its electrode wiring, with an interlayer insulating layer between. In a common electrode formed on an opposite substrate opposite the TFT substrate with a liquid crystal layer between, an alignment controlling window for the liquid crystal is formed at a predetermined position opposite each of the pixel electrodes. A wide viewing angle is achieved by dividing an alignment area of liquid crystal molecules in one pixel area. The liquid crystal layer is vertically aligned and can be operated at a low driving voltage obtained by a poly silicon TFT by including fluorine liquid crystal molecules having negative dielectric anisotropy and fluorine side chains in the liquid crystal.

摘要： Disclosed is a light-emitting display having a plurality of pixels wherein each pixel comprises a light-emitting device (100) having a light-emitting element layer which is formed between a first electrode and a second electrode and contains at least a light-emitting layer. An insulating layer (30) is formed between the light-emitting device (100) and a surface of a first or second substrate on the viewing side of the display, and the insulating layer (30) is provided with recesses and projections in at least one or more pixel regions, thereby forming an optical path length adjusting portion (32). By forming such an optical path length adjusting portion (32) in a pixel region, there is an increase in the interference conditions for the light emitted from the light-emitting device (100) to the outside, thereby averaging the interference.

摘要： A semi-transmissive film is provided underneath a transparent electrode of an organic EL element. The optical length of the interval between the upper surface of the semi-transmissive film and the lower surface of a counter electrode serving as a reflective layer is configured such that this interval functions as a microresonator for selecting light having a specific wavelength. A color filter is provided underneath the semi-transmissive film to further restrict the wavelength of light which has passed through the semi-transmissive film.
