BACKLIGHT MODULE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of achieving a backlight module with little unevenness which can efficiently utilize light with few LED substrates.SOLUTION: In a liquid crystal display module 10, a first light guide plate 52 has a horizontal surface 62a and serrate inclined surfaces 61a integrally formed. A second light guide plate 54 also has inclined surfaces 61b and a horizontal surface 62b integrally formed. The respective inclined surfaces 61a, 61b are formed inclined so that their respective ends are lowered. An LED 22 is arranged on each LED substrate 20 so as to be at a central position in height and width directions of each serrate (a right triangle) shape. Namely, The LEDs 22 are arranged on the LED substrates 20 so as to make one LED 22 correspond to one right triangle shape.
