Abstract
There is provided a light emitting display apparatus including at least a light emitting element and a thin film transistor (TFT) for driving the light emitting element, characterized in that a mechanism is provided in which a semiconductor constituting the TFT is irradiated with at least a part of light whose wavelength is longer than a predetermined wavelength among the light emitted by the light emitting element.
Claims8
A display apparatus comprising:
- a substrate;
- a light emitting element, the light emitting element comprising an anode electrode, a cathode electrode and a layer including a light emitting material;
- a transistor comprising a gate electrode, an oxide semiconductor layer which includes at least any of In, Ga, Zn and Sn, a source electrode and a drain electrode;
- a color filter;
- and
- a sealing member for sealing the transistor and the light emitting element,
- wherein the color filter has an absorption characteristic with respect to a part of light in a wavelength range of shorter than 390 nm and is interposed between the layer including the light emitting material and the transistor,
- wherein the color filter is overlap with the oxide semiconductor layer when viewed from a side of the layer including the light emitting material, and
- wherein the transistor is electrically connected to the light emitting element.
