ABSTRACT:
The generation of residues or flakes of a color filter is suppressed to eliminate conduction failures on an LCD substrate having a color filter on an array substrate. A passivation film formed between a pixel electrode formed in each of a plurality of pixel regions and a TFT for driving the pixel electrode has a multi-layer structure constituted by SiN layers and a SiO layers, and the SiO layer is located at the top of the film. A resin CF layer is formed on the passivation film having such a multi-layer structure. Since the resin CF layer is formed directly on the SiO layer, reduction of the adhesion of the same is suppressed. As a result, the color filter is unlikely to come off when the resin CF layer is formed, and residues of the color filter is unlikely to be generated when a contact hole is formed in the resin CF layer. This suppresses conduction failures and makes it possible to provide a reliable TFT substrate and LCD having high display characteristics.
