Abstract

A color changing substrate comprises a substrate comprising emission areas and non-emission areas, a color filter layer on the substrate and comprising a light blocking member partitioning the emission areas and the non-emission areas, and a plurality of color filters in areas surrounded by the light blocking member, a bank overlapping the light blocking member, a wavelength control layer comprising wavelength conversion layers and a light transmitting layer in areas surrounded by the bank, a reflective layer overlapping the bank, a first metal oxide layer overlapping the reflective layer, and a self-assembled layer overlapping the first metal oxide layer.
