Abstract:
In order to improve the transmissivity of each pixel and the brightness of a high-definition screen, a TFT and a projection are disposed in each pixel, a source electrode of the TFT extends so as to cover the projection, an inorganic passivation film is formed over the TFT and the projection, an organic passivation film is formed on the inorganic passivation film on the TFT, an opposed electrode is formed on the organic passivation film, an upper insulation film is formed over the opposed electrode, a pixel electrode is formed on the upper insulation film, and the pixel electrode is connected to the source electrode through a connection hole formed in the inorganic passivation film and the upper insulation film on the projection. Accordingly, the diameter of a through-hole can be made smaller.
