Abstract
The present invention provides a transflective display device capable of reducing a difference in white balance between transmissive display and reflective display. The display device of the present invention is a transflective display device including three or more filters having different colors in a pixel, each of the three or more filters having different colors, including: a transmissive region for displaying an image by transmitting light from a backlight; and a reflective region for displaying an image by reflecting surrounding light, wherein, in the reflective region of at least one of a plurality of filters having different colors used for displaying white in reflective display, a light-reducing film which reduces an amount of at least light having a peak wavelength of a visible light transmission spectrum of the at least one of a plurality of filters is arranged, and the visible light transmission spectrum is measured using a standard light source D65.
