Color filter and light-emitting display element

A color filter for use in a light-emitting display element which emits at least white light, the color filter comprising:

• a selective reflection layer,
• a filter layer comprising a plurality of filter portion including a white filter portion, and
• a circularly polarizing layer which comprises a polarizing layer,
• the polarizing layer having an orientation layer and a liquid crystal compound layer,
• wherein the circularly polarizing layer and the selective reflection layer are formed only in an optical path of the white light transmitted by the white filter portion.
