  • Display device
    Patent number: 9250456
    Abstract: A display device includes a first substrate, a second substrate, and a plurality of light emitting sections. The first substrate includes a first surface and a second surface which faces the first surface. The second substrate is arranged to face the first substrate, and is configured with a first surface which faces the second surface of the first substrate, and a second surface which faces the first surface. The plurality of light emitting sections is provided on the second surface of the first substrate while being separated from the second substrate. A light transmission suppression layer on which a light transmission section to transmit light from light emitting sections is provided is formed on the second surface of the second substrate in correspondence to each light emitting section. An anti-reflection layer is formed in the light transmission section.
