Abstract:
The present invention makes it possible to improve long-term reliability and useful lifetime of an LED display. Provided is an LED display comprising a TFT, an LED, and a light-shielding film. The LED comprises an LED layer. The TFT and the LED layer are positioned on a substrate. The TFT drives the LED. The light-shielding film is positioned on a lateral surface of the LED layer and shields against light leaking from the lateral surface of the LED layer. The TFT comprises a gate electrode and a semiconductor channel layer. The semiconductor channel layer is positioned on the gate electrode. In plan view from the thickness direction of the substrate, the gate electrode overlaps the whole of the semiconductor channel layer and is larger than the semiconductor channel layer.
