摘要:
A backlight assembly and an LCD having the same are disclosed to prevent wrinklings of optical sheets due to close contact of optical sheets or prism sheets. The backlight assembly includes multiple optical sheets disposed between a light guiding plate and a display unit, for the diffusion of light, collection of light and securing of horizontal viewing angle. The front surface or the rear surface of each of the optical sheets each has an embossing structure or a matte structure to decrease a contact area between the multiple optical sheets and to minimize frictions.
