Definitions

  • the light shielding layer LIL is formed in an island shape independently in the pixel region and hence, it is difficult to anodize the light shielding layer LIL.
  • a parasitic capacitance between the pixel electrode PX (R) and the drain signal line DL or the capacitive signal line CL causes no significant problems because the protective film PAS 1 among the protective films PAS is constituted of an organic material having a comparatively small dielectric constant.
  • the black display is performed in the light transmissive region LTA, the complete black display is not performed on the portion and a frame-like pattern is recognized by naked eyes.
  • the light shielding layer ILI is formed on this portion for overcoming the above-mentioned drawback.
