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

Abstract: A display device includes: a liquid crystal layer disposed between a first substrate and a second substrate; a color conversion layer disposed between the first substrate and the second substrate and including a first light emitter configured to absorb first color light outputted from a light source and to emit second color light that is different from the first color light; a pixel electrode overlapping a display area; a first transistor connected to the pixel electrode; a driving circuit including a second transistor and providing a driving signal to the first transistor; a light blocking member disposed on the first substrate and overlapping the first transistor; and an polarizing layer disposed between the liquid crystal layer and the color conversion layer and including a wire grid pattern overlapping the display area and a reflection pattern extending from the wire grid pattern to overlap the non-display area.
