Title: DISPLAY DEVICE
Abstract:
A display device (100) is capable of switching between and displaying a plurality of display modes including a normal mode and a sports mode. The display device (100) is provided with a display plate (30) and a fixed polarizing plate (40) and rotating polarizing plate (60) positioned in the front surface direction (FD) of the display plate (30). In the normal mode, the polarization directions (AX1, AX2) of the fixed polarizing plate (40) and the rotating polarizing plate (60) are aligned. As a result, a first display part (20) provided on a display surface (31) of the display plate (30) is displayed. On the other hand, in the sports mode, the polarization directions (AX1, AX2) of the fixed polarizing plate (40) and rotating polarizing plate (60) are perpendicular to each other. As a result, the first display part (20) is made to be invisible, and a second display part (120) provided on the rotating polarizing plate (60) emits light as a result of ultraviolet light irradiated by an ultraviolet light source (85).
