Abstract: A light emitting display panel includes a first emission area, a second emission area, and a third emission area spaced apart from each other and emitting different colors of light and a photochromic layer surrounding each of the first, second, and third emission areas and disposed in a non-emission area. When the first emission area, the second emission area, and the third emission area emit light, the photochromic layer is in a transparent state. When light of a wavelength band shorter than visible light is incident on the photochromic layer, the photochromic layer is in an opaque state.
