Abstract
The transistor includes a first insulating film, an oxide semiconductor layer, a gate insulating film, an upper gate electrode, and a second insulating film being sequentially layered on a substrate, and the transistor includes a light blocking layer layered on the second insulating film and formed of metal. The light blocking layer is electrically connected to the upper gate electrode by interposing a gate contact hole provided in the second insulating film. The oxide semiconductor layer is configured such that a region overlapping with the upper gate electrode entirely overlaps with the light blocking layer.
