Abstract: A light emitting display apparatus can include a thin film transistor (TFT) substrate and a color filter substrate. The TFT substrate can include a plurality of pixels, where each pixel includes an emission region and a non-emission region. The color filter substrate can include an upper substrate opposite to the TFT substrate, a color filter layer on the upper substrate, and a black matrix dividing the color filter layer. The black matrix can have an eaves structure.
