Abstract
An exemplary display device (10) includes a display module (11), a frame (12), a porous ceramic member (13), and a transparent protection plate (14). The frame defines a receiving cavity (121). The display module is confined in the receiving cavity of the frame. The transparent protection plate is configured in front of the light output side of the display module. The porous ceramic member is located between the front surface (122) of the frame and the transparent protection plate. The display device can prevent fogs forming on the transparent protection plate for maintaining a clear display.
