Abstract

A liquid crystal display module includes a liquid crystal display panel, a backlight and a frame-shaped mold frame capable of mounting the liquid crystal display panel thereon and housing the backlight. On a flexible printed circuit board which has one end thereof connected to the liquid crystal display panel, a light source is mounted in a state that the light source faces a light incident surface of a light guide plate in an opposed manner. A plurality of electronic components are mounted in the vicinity of the light source. A housing portion for housing the plurality of electronic components is formed in the mold frame. The plurality of electronic components is mounted in a state that terminals of the electronic components are arranged in the direction perpendicular to the light incident surface of the light guide plate.

Claims (17)

1. A liquid crystal display module comprising:

a liquid crystal display panel;

a backlight; and

a frame-shaped mold frame capable of mounting the liquid crystal display panel thereon and capable of housing the backlight therein, wherein

the backlight includes a light guide plate arranged to face the liquid crystal display panel in an opposed manner and a light source arranged to face a light incident side surface of the light guide plate in an opposed manner,

the liquid crystal display module includes a flexible printed circuit board which has one end thereof connected to the liquid crystal display panel and another end thereof configured to mount the light source thereon, and is arranged to surround a frame body constituting the mold frame,

a plurality of electronic components is mounted on a side of the flexible printed circuit board on which the light source is mounted, each of the plurality of electronic components having at least two terminals,

a housing portion for housing the plurality of electronic components is formed in a lower side of the mold frame, and

the plurality of electronic components is mounted on the flexible printed circuit board in a state that the at least two terminals of each of the electronic components are arranged parallel to each other in a direction orthogonal to the light incident side surface of the light guide plate;

wherein the housing portion for housing the plurality of electronic components separates the plurality of electronic components housed therein from the light source which is mounted on the same side of the flexible printed circuit board.

2. A liquid crystal display module according to claim 1 , wherein each of the plurality of electronic components has only two terminals.

3. A liquid crystal display module according to claim 2 , wherein the electronic components are resistors, capacitors or diodes.

4. A liquid crystal display module according to claim 1 , wherein each of the plurality of electronic components has two terminals, three terminals, or four terminals, and the number of two-terminal electronic components is set larger than the total number which is an addition of the number of three-terminal electronic components and the number of four-terminal electronic components.

5. A liquid crystal display module according to claim 4 , wherein the electronic components are resistors, capacitors or diodes.

6. A liquid crystal display module according to claim 1 , wherein the electronic components are resistors, capacitors or diodes.

7. A liquid crystal display module according to claim 1 , further comprising:

pads which correspond to respective ones of the plurality of electronic components arranged on the flexible printed circuit board parallel to each other in the direction orthogonal to the light incident side surface of the light guide plate.
