摘要

PURPOSE: An optical sheet, a light source assembly, and an LCD device thereof are provided to prevent the degradation of the light transmittance by reducing the amount of bubble inside materials. CONSTITUTION: An optical sheet comprises a first material(110) and a second material(120) laminated on the first material. The first material and the second material are composed of a transparent material transmitting light. A adhesive layer(180) sticks the first material and the second material. A third material(130), and a fourth material(140) can be selectively laminated on the second material.
