Abstract

A liquid crystal display device manufacturing method, including the steps of forming first-layer metal patterns in a display portion and a peripheral circuit portion of a first substrate; forming a first insulating film on the first-layer metal patterns; forming second-layer metal patterns on the first insulating film; and forming a color resin film on the second-layer metal patterns. The method also including the steps of patterning the color resin film to form color filters made of the color resin film in a pixel region of the display portion and to leave the color resin film in the peripheral circuit portion and forming a third-layer metal pattern on the color resin film in the peripheral circuit portion.

Claims (12)

1. A liquid crystal display device manufacturing method, comprising the steps of:

forming first-layer metal patterns in a display portion and a peripheral circuit portion of a first substrate;

forming a first insulating film on the first-layer metal patterns;

forming second-layer metal patterns on the first insulating film;

forming a color resin film on the second-layer metal patterns;

patterning the color resin film to form color filters made of the color resin film in a pixel region of the display portion and to leave the color resin film in the peripheral circuit portion; and

forming a third-layer metal pattern on the color resin film in the peripheral circuit portion.

2. A liquid crystal display device manufacturing method according to claim 1 , wherein the color resin film being left in the peripheral circuit portion is at least a red-colored film.

3. A liquid crystal display device manufacturing method according to claim 1 , further comprising the step of:

forming a second insulating film between the second-layer metal patterns and the color resin film.

4. A liquid crystal display device manufacturing method according to claim 1 , further comprising the step of:

forming a planarizing resin film between the color resin film and the color filters and the third-layer metal pattern.
