1. A light emitting display panel, comprising:
a substrate;
a first electrode disposed on the substrate;
a bank overlapping a portion of an upper surface of the first electrode;
a light emitting layer disposed on the first electrode;
a second electrode disposed on the light emitting layer;
an encapsulation layer disposed on the second electrode;
a photochromic layer disposed on the encapsulation layer, and overlapping a portion of the bank,
wherein when a first wavelength band of light is irradiated to the photochromic layer, the photochromic layer is in a transparent state, and
wherein when a second wavelength band of light is irradiated to the photochromic layer, the photochromic layer is in an opaque state, the second wavelength band being shorter than the first wavelength band,
wherein the light emitting display panel includes an emission area and a non-emission area, and
wherein the photochromic layer is disposed in the non-emission area and surrounds the emission area.
