ABSTRACT:
A flat-panel display device, particularly, a liquid crystal display (LCD) and a plasma display panel (PDP), and manufacturing methods therefor are provided. 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.
