Abstract
An optical wave-guide device is provided between a light source and a lower diffuser for deflecting and reflecting the light passing through the optical wave-guide device so that the light is consistently diffused through the lower diffuser without creating any blind area among light sources to effectively solve the prior art problem of displaying bright bands and dark bands on the LCD.
