Display device

A display device worn on an eye portion of a user, comprising:

• a transparent plate disposed such that one principal surface faces an eye of the user when the display device is worn by the user;
• an image light emission device configured to emit image light related to an image to be displayed toward the one principal surface of the transparent plate;
• a transmission hologram provided between the one principal surface of the transparent plate and the image light emission device, and configured to duplicate the image light emitted from the image light emission device to transmit the image light as reproduction light;
• a reflection hologram provided such that one principal surface faces the other principal surface of the transparent plate, and configured to reflect, on the one principal surface, the reproduction light transmitted by the transmission hologram and passing through the transparent plate toward the eye of the user;
• and
• an absorption layer provided on the other principal surface side of the reflection hologram, the absorption layer being formed by combining an absorption member configured to absorb a part of the reproduction light not reflected on the one principal surface of the reflection hologram and a transparent member.
