Abstract: An exemplary light emitting diode includes a main body, a red light emitting chip, a green light emitting chip, and a blue light emitting chip. The main body includes two inner side surfaces opposite to each other and a inner bottom surface connected with the side surfaces. The side surfaces and the bottom surface cooperatively define an accommodating space. The red light emitting chip, the green light emitting chip and the blue light emitting chip are positioned at the bottom surface and the side surfaces of the accommodating space, respectively.

Abstract: An exemplary backlight module (22) includes a light guide plate (21), an illumination device (20), and plural reflection sheets (23). The illumination device is opposite to the light guide plate, and includes a supporting member (242), and plural light emitting diodes (240) formed at the supporting member. The plural reflection sheet is integrally formed with the supporting member.

Abstract: An exemplary light guide plate (2) includes a light output surface (21) on one side of the light guide plate; a bottom surface (22) on an opposite side of the light guide plate; and a plurality of V-shaped refraction interfaces (24) disposed between the light output surface and the bottom surface. The V-shaped refraction interfaces are formed in the light guide plate, which prevents the V-shaped refraction interfaces being pressed by other optical elements. That is, the V-shaped refraction interfaces are secure during assembly and transportation of a backlight module employing the light guide plate. Moreover, the V-shaped refraction interfaces do not occupy a large amount of space, which means that the backlight module can be made thinner.

Abstract: An exemplary liquid crystal display (2) has a liquid crystal panel (50) and a backlight module (20) being disposed under the liquid crystal panel, the backlight module has a light guide plate (21), and a light source having at least one point light source (23), at least one light guide bar (22) transmitting light beams from the at least one point light source, and a reflector (24) reflecting light beams from the at least one light guide bar into the light guide plate.
