Display panel and optical filter

PURPOSE: A display panel and an optical filter are provided to overcome the limitation related to a color and a concentration by obtaining reflective colors using a reflective layer. CONSTITUTION: An optical filter(50) includes a color compensation layer(51) and a reflective layer(52). The color compensation layer controls transmitted light(C10) which is transmitted from inside of a plasma display panel to the outside and obtain a transmittance color. The reflective layer controls the reflected light(C20) which is reflected from the plasma display panel and obtains a reflection color.
