Abstract:
The present invention relates to photoresist solution for phosphor slurry for use in the color cathode ray tube. The photoresist solution of the present invention comprises Diazo or Bisazide photosensitizer; polymer. which is mixed with said Diazo or Bisazide photosensitizer, obtained by polymerization of hydroxy ethyl acrylate base. The photoresist solution of the present invention improves the adhesive strength by using of the Diazo or Bisazide photosensitizer and the polymer, thus the green, blue and red phosphor screen being uniformly formed and the color residue being disappeared. Further, since the photosensitizer not containing heavy metal is used, it does not cause any environmental problem. Also, it can be stored for a long time by using the initiator without hydrochloric acid at the time of polymerization.
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.
