Title:
Display device
Document Type and Number:
Japanese Patent JP6014086
Kind Code:
B2
Abstract:
A structure for preventing deteriorations of a light-emitting device and retaining sufficient capacitor elements (condenser) required by each pixel is provided. A first passivation film, a second metal layer, a flattening film, a barrier film, and a third metal layer are stacked in this order over a transistor. A side face of a first opening provided with the flattening film is covered by the barrier film, a second opening is formed inside the first opening, and a third metal layer is connected to a semiconductor via the first opening and the second opening. A capacitor element that is formed of a lamination of a semiconductor of a transistor, a gate insulating film, a gate electrode, the first passivation film, and the second metal layer is provided.
