Abstract
A display device includes: a backlight unit emitting a light; a first substrate on a path of a light emitted from the backlight unit; a pixel electrode on the first substrate; a light amount control layer on the pixel electrode; a first polarizer on the light amount control layer; a color conversion layer on the first polarizer; and an angular filter between the backlight unit and the color conversion layer. The color conversion layer includes a phosphor, and the angular filter blocks 50% or more of a light incident to the angular filter at an incident angle of 30 degrees or more.
