Abstract

A liquid crystal display device is provided wherein decline of the driver IC's drive performance due to transmission of heat from the light source is prevented, and which is equipped with a light source of good luminous efficiency that can realize high brightness even when the LEDs are small-sized. Such a liquid crystal display device 1 comprises: an edge light type backlight device 2 having a light guide plate 21 and a light source 22 that is deployed close to an edge surface of said light guide plate 21; and a liquid crystal display panel 3 wherein a pair of substrates 31 , 32 are deployed facing each other, a liquid crystal layer is formed between the two substrates 31 , 32 , and a driver IC 33 for driving the liquid crystal is mounted on one substrate 31 of said pair of substrates 31, 32 . Such liquid crystal display panel 3 is placed over said backlight device 2 to form the liquid crystal display device 1 , wherein said driver IC 33 is placed close to an edge other than the edge where the light source 22 of said backlight device 2 is located. Also, the light source 22 is made up of one or more LEDs.

Claims (7)

1 . A liquid crystal display device comprising:

an edge light type backlight device having a light guide plate and a light source that is deployed close to an edge surface of said light guide plate; and

a liquid crystal display panel wherein a pair of substrates are deployed facing each other, a liquid crystal layer is formed between the pair of substrates, and a driver IC for driving the liquid crystal is mounted on either one of said pair of substrates;

the liquid crystal display panel being placed over said backlight device;

said driver IC being placed close to an edge other than the edge where the light source of said backlight device is located.

2 . The liquid crystal display device according to claim 1 , wherein said light source comprises at least one light-emitting diode.

3 . The liquid crystal display device according to claim 1 , wherein said driver IC is placed at the opposite edge of said liquid crystal display panel to the edge where said light source of said backlight device is deployed.
