Abstract:
1. A display apparatus comprising: a substrate; a light emitting element having an anode electrode, a cathode electrode and a light emitting layer; a thin film transistor for driving the light emitting element, the thin film transistor comprising a gate electrode, a gate insulating layer, a semiconductor layer which includes an oxide semiconductor, a source electrode, and a drain electrode; and a color filter located on an optical path from the light emitting element to the semiconductor layer, wherein the color filter has a specific spectral absorption property so as to attenuate a light with a shorter wavelength than an absorption edge wavelength of the oxide semiconductor and selects light irradiated from the light emitting element to the semiconductor layer with regard to a wavelength, and wherein the source electrode of the thin film transistor is connected to the anode electrode through a contact hole.
