摘要： A method for controlling the cell gap of a liquid crystal display device is disclosed. A photo-sensitive polymer layer is coated over a substrate on which color filter, ITO and black matrix of the liquid crystal display device are formed. Spacers are uniformly sprayed and adhered on the photo-sensitive polymer. With a negative-type photo-polymer, a photo-mask can be used to expose the area of photo-sensitive polymer layer covering the the black matrix. The masked area is exposed, developed and removed by a conventional photo-lithographic process. The spacers attached to the masked area are also removed. The size of the spacers attached on the polymer above the thin-film transistors and the black matrix controls the cell gap.

摘要： The method includes patterning red, green and blue pixels (R, G, B) on a substrate. A transparent positive type photoresist is coated on the color pixels. A first exposure is performed by an illumination using a photomask having an opening aligned to the red pixels (R). Next, the photomask is relatively shift to a position such that the opening is aligned to the green pixels (g). Then, a second exposure is carried out to expose the positive photoresist. Similarly, the photomask is also shift such that the opening is aligned to the blue pixels. Subsequently, the positive photoresist is exposed by the illumination by using the photomask. The positive photoresist is exposed by controlling the intensity of the illumination, exposure time or the combination thereof. Then, the positive photoresist is developed by conventional manner. Subsequently, a color filter plate with multi-gap for LCD is formed.

摘要： A liquid crystal display device comprises extended polymer networks formed in the liquid crystal cells. By adding a monomer and a photo-initiator into the liquid crystal material of a liquid crystal display, applying a bias voltage and exposing the display under a UV light, a polymer network can be formed. The polymer network modifies the electro-optical characteristic of a liquid crystal display device. With different bias voltages, polymer networks of different structures can be formed so that the color difference of the liquid crystal display with respect to red, green and blue light can be minimized. Liquid crystal display devices of fast switching response and low color dispersion can be fabricated.

摘要： A method for manufacturing a liquid crystal display having both wide angle viewing and fast response is described. A key feature of the method is the addition to the liquid crystal of a small amount of a monomer, selected from among the diacrylates or the monoacrylates, as well as a chiral dopant. Once the display has been assembled, the usual turn-on voltage (about 5 volts) is applied. After allowing the orientations of the directors to stabilize, the liquid crystal is irradiated with ultraviolet light for a few seconds. This causes the dissolved monomer to polymerize in place. The UV irradiation and applied voltage are then terminated. Defects that slow down the director stabilization are now prevented from re-forming so that the next time voltage is applied, the system responds in a few milliseconds. Adding a photoinitiator, in addition to the monomer, is an option.
