Abstract
A display device is provided in which all indicators can be illuminated with substantially uniform brightness irrespective of the distance of the indicators from the light source or the positional relationship of the indicators. A light guide (11) guides light emitted from a light source (20). A design display (12) has a light emitter (122) for emitting light. A low-refractive-index portion (14a) having a lower light refraction index than the light guide (11) is installed between the light guide (11) and the design display (12). A light-diffusing portion (13) is formed in the light guide (11), and light guided by the light guide (11) is diffused. A display light adjuster (15) for changing the emission efficiency is provided at least inside a region corresponding to the light emitter (122).
