First claim

The invention claimed is:

1 . A display apparatus, wherein the display apparatus comprises a display surface for display, and the display apparatus comprises:
a touch screen, the touch screen comprising a first functional layer and a touch sensing layer which are stacked, the first functional layer being disposed on a side of the touch sensing layer facing the display surface, and the touch sensing layer receiving external touch; a display screen, the display screen comprising a liquid crystal panel and a backlight module which are stacked, the liquid crystal panel being disposed on a side of the touch sensing layer facing away from the display surface, the backlight module being disposed on a side of the liquid crystal panel facing away from the display surface, a second functional layer being disposed between the liquid crystal panel and the touch sensing layer, and a third functional layer being provided between the liquid crystal panel and the backlight module; and an adhesive, the adhesive being disposed between the touch screen and the display screen and used to bond the touch screen and the display screen, wherein at least two of the first functional layer, the touch sensing layer, the adhesive, the second functional layer, and the third functional layer are provided with an anti-glare structure and an anti-blue light structure.

2 . The display apparatus according to claim 1 , wherein,
the first functional layer is a transparent cover plate, and the anti-glare structure and the anti-blue light structure are provided on a surface of the transparent cover plate facing the touch sensing layer.

3 . The display apparatus according to claim 2 , wherein,
the anti-glare structure is directly formed by surface etching, or the anti-glare structure is formed by spraying or coating an anti-glare material.

4 . The display apparatus according to claim 3 , wherein,
the anti-glare structure and the anti-blue light structure are formed by spraying or coating an anti-glare material and an anti-blue light material respectively.

5 . The display apparatus according to claim 3 , wherein,
the anti-glare structure and the anti-blue light structure are formed together by spraying or coating a mixed material of an anti-glare material and an anti-blue light material.

6 . The display apparatus according to claim 1 , wherein,
the first functional layer is a transparent cover plate, and the anti-glare structure and the anti-blue light structure are provided on a surface of the transparent cover plate facing away from the touch sensing layer.
