Abstract: A method for manufacturing a color filter by thermal transfer using a laser beam with uniform energy distribution. The method includes forming a black matrix pattern on a substrate by photolithography. A transfer film having thermal color layers is placed on the substrate, and a laser beam with uniform energy distribution irradiates the transfer film to transfer the color layers onto the substrate. The substrate onto which the color layer has been transferred, is cured at 200˜300° C. Therefore, by using the laser beam with uniform energy distribution, or a laser beam which scans by dithering, for the thermal transfer, the quality of an image formed at the edges of the is improved and the surface roughness is reduced, resulting in an excellent color filter.

To form spacers or barrier walls which locate between upper and lower substrates of the LCD or PDP to maintain the gap between two substrates to a predetermined distance, a laser transcription method is used. That is, a donor film including a base film, a light absorption layer and a transcription layer is put on the lower substrate of the LCD, in which a transparent substrate, a transparent electrode and an alignment layer are stacked in sequence, or on the lower substrate of the PDP, in which a transparent substrate, an address electrode and a dielectric layer are stacked in sequence, and then a laser beam is transcribed thereonto to form the spacers or barrier walls having uniform height and width. Therefore, the interval between two substrates is uniform, so that display characteristics can be enhanced through a simple manufacturing process.
