Abstract
The relative positions of a first low-reflection layer and a second low-reflection layer are variable in a bendable portion. A main low-reflection structure has, on a surface facing a secondary low-reflection structure, an asperity pattern and a moth-eye structure. The asperity pattern has a sine-wave shaped surface in a sectional view. A single period of a sine wave constituting the sine-wave shaped surface is equal to an integral multiple of the width of a single pixel of a display device in a direction where the asperity pattern is arranged.
Claims6
A display device including a bendable portion that is bendable, comprising:
- a display device body having a display surface, and having a first low-reflection layer constituting the display surface;
- and
- a cover member covering the display surface, and having a second low-reflection layer facing the first low-reflection layer,
- wherein relative positions of the first low-reflection layer and the second low-reflection layer are variable in the bendable portion,
- a main low-reflection structure has, on a surface facing a secondary low-reflection structure, a first asperity pattern and a first moth-eye structure provided on a surface of the first asperity pattern, the main low-reflection structure being one of the first low-reflection layer and the second low-reflection layer, the secondary low-reflection structure being another of the first low-reflection layer and the second low-reflection layer,
- the first asperity pattern has a first sine-wave shaped surface in a sectional view, and
- a single period of a sine wave constituting the first sine-wave shaped surface is equal to an integral multiple of a width of a single pixel of the display device in a direction where the first asperity pattern is arranged.
