OPTICAL EXTRACTION ELEMENT, METHOD FOR MANUFACTURING THE OPTICAL EXTRACTION ELEMENT, AND DISPLAY DEVICE

摘要

Provided is an optical extraction element having both a reflector function and a color filter function. The optical extraction element (23) comprises a transparent unit (26) having a reflecting surface for converting the emanating angle of a light from a light emitting layer (21), and the transparent unit (26) is formed at least partially as color filters (26R, 26G and 26B). The transparent unit (26) has a function as a reflector to change the emanating angle of the light from the light emitting layer (21), thereby to improve the extraction efficiency of the light from the light emitting layer (21) to an air layer (8). Moreover, the transparent unit (26) is formed at least partially as a color filter so that it can constitute the reflector and the color filter on a common layer. As a result, it is possible to acquire the optical extraction element which has both the reflector function and the color filter function.
