Abstract

The backlight device includes: a light guide plate (8) having a rectangular shape; LEDs (12) arranged on end surfaces (8a) of side surface portions formed of long and short sides of the light guide plate; and LED board (11) having a long and thin shape and on which the LEDs (12)are mounted, wherein a plurality of LED boards of a same type are arranged on the long and short sides of the light guide plate, and the plurality of LED boards are continuously arranged corresponding to the entire area of the end surface of each side of the light guide plate, and at the same time, the LED boards (11) of any one of long and short sides are not arranged but a predetermined interval is formed at an edge portion constituting a point of contact between the long and short sides of the light guide plate.

Description

technical field [0001] The present invention relates to a backlight device and an image display device, in particular to a backlight device and a backlight device in which light is irradiated from the back of a display panel by using a plurality of point light sources such as light emitting diodes (LEDs) to enter from the side surface of a light guide plate, that is, the end surface. image display device. technical background [0002] In recent years, monitors and image display devices such as televisions that display images using display modules such as liquid crystal panels have spread rapidly. [0003] Generally, the components of an image display device include a display panel part, that is, a main body of the image display device, and a stand, that is, a base part. Among them, the display panel unit includes a display module and a housing that accommodates the display module inside and exposes an image display surface of the display module so as to be visible from the ...
