摘要：
The present invention realizes a bright image display by enhancing a numerical aperture of pixels. At least a portion of a pixel electrode is overlapped to a thin film transistor by way of a first insulation film, the pixel electrode is connected to an output electrode of the thin film transistor via a contact hole which is formed in the first insulation film, the counter electrode is arranged above the pixel electrode by way of a second insulation film in a state that the counter electrode is overlapped to the pixel electrode, the counter electrode is formed at a position avoiding the contact hole formed in the first insulation film as viewed in a plan view, and at least a portion of the counter electrode is overlapped to the thin film transistor.
