A light extraction device having a reflector function and a color filter function are provided. A light extraction device includes a translucent portion having a reflection surface for changing an exit angle of light from a light-emitting layer, and at least a part of the translucent portion is formed as color filters. The translucent portion has a function as a reflector for changing the exit angle of light from the light-emitting layer, and improves an extraction efficiency of light from the light-emitting layer to an air layer. Further, the at least a part of translucent portion is formed as the color filters, and therefore a reflector and the color filter can be formed on the same layer. With this structure, the light extraction device having the reflector function and the color filter function can be obtained.
