The liquid crystal screen light guide plate structure also comprises a light source 6, wherein light rays emitted by the light source 6 enter the mesh points 3 through refraction of the light guide plate 1 and reflection of the reflection paper 2, and are projected onto the membrane 4 to form an image after refraction and reflection of the mesh points 3. Optionally, the dots 3 are circular bulges, and light is emitted out in a fan shape under the scattering action of the circular bulges, so that the overall display effect of the liquid crystal display screen is improved.
Because the surface of the light guide plate 1 is smooth, the direct bonding effect with the mesh points 3 is poor, the bonding strength is low, and the falling-off condition is easy to occur. Through the one side at the laminating of reflection paper 2 and light guide plate 1, set up coarse structure 21 to set up site 3 on the coarse structure 21 of reflection paper 2, can realize the refraction and the reflex action of the light that site 3 sent light source 6, through increasing the adhesive capacity between site 3 and the reflection paper 2, make site 3 be difficult for droing, improve LCD screen light guide plate structure's overall reliability and life.

Optionally, the size and shape of the reflective paper 2 and the light guide plate 1 are substantially the same, a double-sided tape 22 is disposed on the edge of the reflective paper 2, and the other side of the double-sided tape 22 is adhered to the corresponding edge of the light guide plate 1, so as to fixedly connect the reflective paper 2 and the light guide plate 1.
