Title:
DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2014160667
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a display device with excellent visibility and a function of preventing reflection, capable of further preventing reflection of external light.SOLUTION: A display device includes an anti-reflection film having a plurality of convex parts on a surface of a display screen and a protective layer formed to fill space between the convex parts. The convex parts have a flat upper surface. The external light is reflected not toward the visible side but toward the adjacent convex part. The number of times of light, in the external light entering the display device, entering the anti-reflection film is increased, and the external light reflecting toward the visible side is reduced, thereby preventing the deterioration in visibility such as reflection. Moreover, since the space between the convex parts is covered with the protective layer, the entry of dust can be prevented and the physical strength of the anti-reflection film can be increased.
