Problems solved by technology
Therefore, it is difficult to further reduce the number of parts, and there is a problem that cost reduction is difficult
[0023] In addition, in the above-mentioned structure, it is necessary to connect the wiring to the front and back substrates through the holes in the chassis when assembling the module. On the other hand, if the process of passing such wiring through the hole is included in the assembled structure, the workability will be very poor, and the man-hour will increase.
Therefore, there is such a problem that it takes manufacturing cost
[0024] In addition, liquid crystal display devices sometimes use the same wiring or light-emitting element substrate and different power supply substrates due to their different characteristics. The connector is mounted on the power board
Therefore, the degree of freedom in the design of the power board is small, and there is a problem of cost.

Provided is a backlight assembly wherein a cost reduction is easier than conventional. A backlight assembly (1) has light-emitting element boards (23a to 23f) that are mounted with light-emitting elements (31) and provided on a frame (3b) around an upper surface (front surface) of a chassis (3), a power supply board (51) that is provided on a back surface of the chassis (3) and supplies power to the light-emitting element boards (23a to 23f), and a relay connector (21) that is held by the chassis (3) and electrically connects between the power supply board (51) and the light-emitting element boards (23a to 23f).
Description
technical field [0001] The invention relates to a backlight assembly, a relay connector used in the backlight assembly, and a backlight unit with the backlight assembly. Background technique [0002] Display devices using liquid crystals are lighter, thinner, and consume less power than display devices such as cathode ray tubes, and thus are widely used in display devices such as portable devices, computers, and large televisions. [0003] On the other hand, since the liquid crystal itself does not emit light, in order to display a screen, a backlight unit that irradiates light from behind the liquid crystal is often required. [0004] A backlight unit requires a backlight assembly, which includes: a light-emitting element substrate having a light-emitting element such as an LED (Light Emitting Diode); a power supply substrate that supplies power and control signals to the light-emitting element; Conductive circuits such as wires. [0005] As a specific structure of the ba...
