Classification: CPC H | IPC H

Claim 0:
1. A display apparatus, comprising:
a base substrate;
a thin film transistor layer on the base substrate;
an insulation layer on the thin film transistor layer;
a first electrode made of a reflective metal disposed on the insulation layer and in a light emitting area, the reflective metal being a different material than metal constituting wirings of the thin film transistor layer;
a pixel defining layer on the insulation layer, the pixel defining layer having an opening that has a substantially same size and a substantially same shape as the top surface of the first electrode at a location of the top surface of the first electrode;
a light emitting layer on the first electrode; and
a second electrode on the light emitting layer, wherein
a light transmittance of the insulation layer in a wavelength range of 300 nm to 500 nm is lower than that of the pixel defining layer, and
the insulation layer absorbs light having a wavelength in a range from about 300 nm to about 500 nm.
