Abstract
A display device and a method for adjusting a chromaticity of a display beam are provided. A display device includes a light source module, a viewing angle switching module and a display module. The light source module includes a light source used for providing a light beam, and an illumination beam is formed by the light beam through the light source module, wherein the chromaticity of the light beam falls within a first region in the CIE 1931 xy chromaticity coordinates. The first region is a region enclosed by four coordinate points, and values of the four coordinate points of the first region are (0.2535, 0.2160), (0.2656, 0.2590), (0.2795, 0.2590), and (0.2674, 0.2160), respectively. The viewing angle switching module and the display module are located on the transmission path of the illumination beam.
