Side paste for improving brightness and light guide plate structure

The utility model discloses a side paste and a light guide plate structure for improving brightness, the side paste comprises a reflection base material and a colloid layer attached on the reflection base material, the side paste also comprises a reflection layer, the reflection layer is fixed on the surface of the reflection base material opposite to the colloid layer and is embedded in the colloid layer, and one side surface of the reflection layer far away from the reflection base material is a zigzag reflection surface. The side paste can reduce light emitted out of the light guide plate so as to improve brightness. 本实用新型公开一种提升辉度的侧帖及导光板结构，上述侧帖包括反射基材和贴合在反射基材上的胶体层，还包括反射层，反射层固定在反射基材的与胶体层相对的面上并埋入胶体层中，反射层远离反射基材的一侧面为锯齿状反射面。本实用新型的侧帖能够减少光线射出导光板而提高辉度。
