摘要:
This organic-EL display apparatus comprises an organic-EL display panel including: a substrate that is provided with pixel drive circuits to drive respective pixels arranged in a matrix along each of a first direction and a second direction, and organic light-emitting elements being provided to each of the pixels and connected to any one of the pixel drive circuits. The organic-EL display panel comprises a signal output circuit to supply a signal to each of the pixel drive circuits arranged in a line along the first direction or the second direction. The signal output circuit includes thin film transistors and is formed around a display region on a surface of the substrate. The thin film transistors include a semiconductor layer including a region to be a channel between a source electrode and a drain electrode. The semiconductor layer is formed of amorphous silicon.
