Abstract: A display device includes a display panel and a light source configured to provide a first color light to the display panel. The display panel includes a first display substrate (DS), a second DS facing the first DS, a column spacer disposed between the first and second DSs, and a liquid crystal layer filled between the first and second DSs. The first DS includes: a first base substrate (FBS); a thin film transistor (TFT) disposed on the FBS, the TFT including a gate electrode, first and second electrodes, and an activation layer; a first insulation layer (IL) covering the TFT and disposed on the FBS; and a second IL disposed on the first IL and including an opening exposing a first portion of the first IL overlapping the activation layer. The column spacer is disposed on the first portion to cover the activation layer and shield the first color light.

Abstract: Provided is a display panel in which a first pixel region, a second pixel region, a third pixel region, and a light-blocking region may be defined. The first substrate may include a base layer; a first color filter layer overlapping the light-blocking region and the first pixel region; a light blocking layer overlapping the light-blocking region; a second color filter layer overlapping the second pixel region; a third color filter layer overlapping the third pixel region; and a step compensation layer disposed on one surface of the light-blocking layer and configured to cover at least a portion of the light-blocking region adjacent to the first pixel region when viewed in a plane.

Abstract: A display apparatus includes a display panel including a base layer in which an active area and a peripheral area adjacent to the active area are defined, and a plurality of pixels, and a cover panel including a window layer, an optical filter layer disposed on a rear surface of the window layer, and a color filter layer disposed on the optical filter layer and including quantum dots. The optical filter layer includes a partition layer in which an opening is defined and which includes an organic material, a light blocking layer disposed on the partition layer, and a reflective layer disposed in the opening. The light blocking layer includes a metal.
