We have developed a high quality and simplified multigap color filter (MCF). Amultigap LCD is effective for reduction of color dispersion and improvement of viewing angle. A MCF is achieved by applying a single-layer of transparent positive type photo resist to the multigap color filter. The gap difference is easily determined by controlling amount of the UV exposure. The high degree of flatness of MCF, compared to that obtained by double-layer of transparent negative type photo resist, will be shown. Investigation of the influence of post exposure process on the transmittance will also be reported. The high quality, simplified MCF with only one additional coating of photo resist to color filter is easy to apply to many types of LCD, such as OCB and normally black TN for performance improvement.
