    摘要： In a liquid crystal display (LCD) device, an LED PCB with the reflection layer formed on surface thereof is installed at an upper side of the LED array and a reflection plate extends such that it sufficiently covers the lower portion of the LED array to thus make light emitted from the light source incident to its maximum level, thus coping with the reduction in the quantity of light resulting from making the LCD device thinner. The LCD device includes: a liquid crystal panel; an LED array supplying light to the liquid crystal panel; a light guide plate installed in a direction in which the LED outputs light, and guiding light; a reflection plate formed between the LED array and a lower portion of a lower cover; and an LED PCB attached to an upper portion of the lower cover at an upper side of the LED array and having a reflection layer formed at a side facing the light guide plate. Because an existing LED housing reflector is removed, a cost and processing time can be reduced and an assembling process is simplified to improve a defective rate and production yield.
