Patent ID: 8841836

Claim:
A flat panel display device comprising: a transparent display panel comprising a front transparent substrate, a back transparent substrate and a pixel array interposed between the front and back transparent substrates; the pixel array comprising a plurality of pixels and a plurality of transparent areas, each transparent area having sufficient transparency to transmit visible light such that light beams incident on the front transparent substrate pass through one or more of the transparent areas of the pixel array and further pass through the back transparent substrate; a first anti-reflective film which is formed over a surface of the front transparent substrate and comprises a moth eye structure; a second anti-reflective film which is formed over a surface of the back transparent substrate and comprises a moth eye structure, wherein the second anti-reflective film is configured to inhibit reflection, back toward the front transparent substrate, of light beams that have passed through one or more of the transparent areas and reached the second anti-reflective film; and a first light-absorbing film covering the transparent areas when viewed in a direction perpendicular to a major surface of the front transparent substrate, the first light-absorbing film being interposed between the transparent display panel and the first anti-reflective film, the first light-absorbing film being configured to absorb at least a portion of light having a wavelength within a range of about 350 nm to about 800 nm.
