Abstract:
1. A method of manufacturing a liquid crystal display, comprising the steps of: forming a switching device over an insulating substrate; forming a metal line over the insulating substrate; forming an interlayer insulating film over the switching device; forming a pixel electrode over the interlayer insulating film; forming trenches right above the switching device and the metal line, the trenches being formed in the interlayer insulating film and to have at least a width greater than a width of the metal line; depositing a black resin on the interlayer insulating film and within the trenches; and developing the black resin to remove a part of the black resin within the trenches to expose the upper part of the pixel electrode and a bottom surface of the trenches to form a black matrix within the trenches over the insulating substrate.
