| 摘要 | A light guide plate includes a light incident surface and a plurality of micro cylinders protruding from the light incident surface in parallel. Each of the micro cylinders has a circumference surface and two opposite end surfaces. The circumference surface is connected to the light incident surface. The two end surfaces are positioned on two opposite ends of the circumference surface, and are perpendicular to the light incident surface. Each of the two end surfaces is circular arc-shaped, and the radius of each of the two end surfaces is in the range of 0.04 μm to 0.07 μm. | ||
