  • Patent number: 10192522
    Abstract: A display device includes a first display surface displaying vehicle information; and a second display surface which is disposed facing the first display surface and transmits light, has a drawing pattern drawn across a display area and outside the display area of the first display surface when seen from a direction in which the second display surface is stacked on the first display surface, and can switch to a displayed state in which the drawing pattern is displayed and a hidden state in which the drawing pattern is hidden. The display device displays information by the first display surface and the second display surface. The display device can therefore realize a visual effect that makes the display area look relatively large.
