Abstract
The present application discloses a light guide plate and a display device. The light guide plate has a light emitting surface configured to guide light out, the light emitting surface is provided with first micro structures, and the first micro structures protrude from the light emitting surface; the first micro structures are gradually tightly arranged on the light emitting surface inwards from the light incident surface; widths of the first micro structures gradually reduce inwards from the light incident surface. Light passes through the first micro structures protruding from the light emitting surface, an incident angle is reduced, so that the light is not prone to generate total reflection, a penetration rate of the light on the light emitting surface of the light guide plate is improved, and a light utility rate is increased.
