    摘要: A method for manufacturing a glass light guide plate having high transmission efficiency is provided. A glass plate is cut and formed using a cutter machine. The glass plate includes a first flat surface and a second flat surface that are opposite and parallel to each other, and a light incident surface perpendicular and connected to the first flat surface and the second flat surface. The light incident surface is heated and extruded using a thermoplastic machine to deform the light incident surface to form a light guide portion. The light guide portion includes a light guide surface perpendicular to the first flat surface and the second flat surface, and has an area greater than an area of the light incident surface. When a light enters via the light guide surface, the amount of light irradiating corners of the light guide surface is reduced.
