Anti-glare glass and display device

Abstract

An anti-glare glass and a display device. The anti-glare glass comprises a glass substrate, wherein one surface of the glass substrate is a reflecting surface, some regions of the reflecting surface are recessed inward to form a plurality of pits, and the edge contour of any pit forms a Thiessen polygon. 200-300 pits are formed in an observation region of the reflecting surface, the diameter of each pit is 10-30 μm, and in the observation region, the distance between the centers of two adjacent pits is 20-30 μm, and the observation region has a length of 320 μm and a width of 240 μm. The anti-glare glass satisfies at least one of the following conditions: (1) the distinctness of image is 0-3; (2) the visible light transmittance is not less than 91%; (3) the transmission haze is 30%-40%; and (4) the glossiness is 10-20. The anti-glare glass not only has a good anti-glare function, but also when used in a display device, provides good clarity and uniform brightness distribution, and is less prone to sparkle.
