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: A display device including: a display panel; a light source providing light to the display panel; and a color conversion unit converting a color of the light incident from the light source into a different color. The color conversion unit includes: a first color converting member, a second color converting member, and a third color converting member, located on a substrate, which convert the color of the light incident from the light source into different colors from each other, respectively, and output the lights having converted colors; and a blue light blocking filter located to overlap the second color converting member and the third color converting member. The blue light blocking filter is thicker at a boundary portion than at a center portion thereof.
