Original Abstract Submitted
The present invention has been made to improve the anti-reflection effect of a light shielding film on the upper surface of a through-hole and provide improved image quality. Disclosed is a liquid crystal display device including a TFT substrate and a counter substrate. The TFT substrate is configured such that a pixel electrode and a common electrode are formed on an organic passivation film, and that a through-hole for connecting the pixel electrode to a TFT is formed in the organic passivation film. A capacitor insulating film is formed between the common electrode and the pixel electrode. A light shielding film is formed and layered on the common electrode. The through-hole is filled with resin. At the upper surface of the through-hole, the capacitor insulating film is formed on the resin. The light shielding film and the common electrode are formed on the capacitor insulating film.
