Liquid crystal display with pixels having an opening formed from a photosensitive resin with spacers attached |
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.
