  • a color TFT-LCD is manufactured in several steps of forming, on a transparent substrate such as a glass, a color filter forming a black matrix resin and a pixel consisting of red (R), green (G) and blue (B); forming on the color filter a transparent conducting film as an electrode using a sputtering method; forming an alignment layer on the transparent conducting film; and filling a liquid crystal into the LCD.
  • the resist has been widely used to form patterns of the color TFT-LCD such as an overcoat, a photo spacer, a color filter, a black matrix, etc.
  • patterns of the color TFT-LCD such as an overcoat, a photo spacer, a color filter, a black matrix, etc.
