Abstract:
An organic EL display apparatus includes a substrate, and a pixel circuit provided for each pixel. The pixel circuit includes a first oxide semiconductor TFT having a first oxide semiconductor layer, and a second oxide semiconductor TFT having a second oxide semiconductor layer. The first oxide semiconductor TFT has a top-gate structure. The second oxide semiconductor TFT has a bottom-gate structure. The second oxide semiconductor TFT has a shield electrode that is disposed on an insulating layer disposed on the second oxide semiconductor layer, facing the second oxide semiconductor layer.
