In addition, the LCD having the above-described structure is complicated in the assembling process due to a large number of components, takes a long time to be assembled, and thus has a disadvantage in that the production amount is reduced and the manufacturing cost is increased.

2, a plurality of LEDs 14b are mounted on the substrate 14a at regular intervals to constitute an LED light source 14, Light from a plurality of point light sources emitted from the light source 14 is incident into the light guide plate 13. [ At this time, most of the light emitted from the LED 14b is incident into the light guide plate 13 to be converted into a surface light source, but a part of the light L is dispersed in the space 11a of the light- The light is directly emitted to the outside through the minute gap between the optical sheet 15 and the guide panel 16 and appears as a light leakage phenomenon.
