Kile Park Reed & Houtteman PLLC
Display device
A display device includes a pixel including a light emitting element connected to a scan line and a data line; a driving transistor that controls a driving current supplied to the light emitting element according to a data voltage applied from the data line. The driving transistor includes a first semiconductor layer, and a first gate electrode disposed on the first semiconductor layer. The display device includes a switching transistor that applies the data voltage to the driving transistor according to a scan signal applied to the scan line. The switching transistor includes a second semiconductor layer, and a second gate electrode disposed on the second semiconductor layer. The display device includes a light blocking layer and a first buffer layer disposed at a lower portion of the driving transistor. The light blocking layer and the first buffer layer do not overlap the switching transistor.
