Problems solved by technology

[0007] MCPCB and FR-4 PCB are more expensive and take up most of the bottom plate of the container
Therefore, the manufacturing cost of the direct-illumination type backlight assembly increases
[0008] In addition, although the PCB includes a material with sufficient heat dissipation characteristics, conduction of heat generated from the LED to the outside through the PCB leads to a decrease in cooling efficiency

Abstract

A backlight assembly includes a light-generating unit and a receiving container. The light-generating unit includes at least one point light source generating light and a power supply line transferring power for driving the point light source. The receiving container receives the light-generating unit, and the power supply line is formed on an insulating layer included in the receiving container.

Description

technical field [0001] The present invention relates to a backlight assembly, a method of manufacturing the backlight assembly, and a display device having the backlight assembly. More particularly, the present invention relates to a backlight assembly having reduced manufacturing costs and improved cooling efficiency, a method of manufacturing the backlight assembly, and a display device having the backlight assembly. Background technique [0002] Generally, as a flat panel display device, a liquid crystal display (LCD) device displays images using electrical and optical properties of liquid crystals. [0003] The LCD device includes a liquid crystal control unit that controls a liquid crystal material, and a light supply unit that provides light to the liquid crystal. For example, an LCD device includes an LCD panel serving as a liquid crystal control unit and a backlight assembly serving as a light providing unit. [0004] The backlight assembly includes a light source ...
