Abstract:
A display device includes a display member, a lens, and a light intensity adjuster. The display member is configured to display an image by releasing relatively short-wavelength light and relatively long-wavelength light. The lens is configured to allow the image on the display member to be reproduced on an eye of the user and thicker in the middle thereof than at the periphery thereof. The light intensity adjuster is included in the display member. The light intensity is configured to allow short-wavelength light to be released from a middle of the display member in a larger amount than both short-wavelength light to be released from ends of the display member and long-wavelength light to be released from the middle of the display member.
