    • The present invention relates to an optical member, comprising: a light incidence surface; and a light-emitting surface which comprises a patterned portion intended for adjusting the intensity of light and formed at an area corresponding to a light source, and an adhesive portion disposed in an area other than the patterned portion. When the optical member of the present invention is applied to a backlight unit, the patterned portion, which diffuses the light from the light source, is formed in the area corresponding to the light source so as to effectively diffuse the light from the light source into the peripheral area. Also, the optical member and a diffusion plate are stacked via an air layer in the area corresponding to the light source (the area in which the patterned portion is disposed), and the optical member and the diffusion plate closely contact each other without an air layer in the remaining area, such that the intensity of the light transmitted between a light source portion and the peripheral portion may be adjusted with an improvement in the balance of brightness and uniformity.
    • 本发明涉及一种光学构件,包括:光入射表面; 以及发光面,其包括用于调节光强度并形成在与光源对应的区域的图案部分,以及设置在图案部分以外的区域中的粘合部。 当将本发明的光学构件应用于背光单元时,在与光源对应的区域中形成扩散来自光源的光的图案部分,以便有效地将来自光源的光扩散到 周边地区。 此外,光学构件和扩散板通过空气层在与光源(设置图案部分的区域)相对应的区域中堆叠,并且光学构件和扩散板在没有空气的情况下彼此紧密接触 从而可以通过改善亮度和均匀性的平衡来调节在光源部分和周边部分之间传输的光的强度。
