Embodiment Construction

[0016] Various exemplary embodiments will now be described in detail. In describing specific technical features related to the exemplary embodiments, these features will be better clarified with reference to the accompanying drawings.

[0017] In the description of the embodiments, it is to be understood that when a layer (or film), region, pattern or structure is referred to as being "on" or "under" another structure, it can be on the other structure directly or indirectly. Thus, it may be in contact with another structure, or alternatively it may not be in contact with another structure, but include an intermediate layer therebetween. "On" and "Under" can be better understood with reference to the accompanying drawings.

[0018] In the drawings, the size of each element is exemplary and their size may be exaggerated for clarity. Therefore, the size of each element may differ from the actual size of the processed product.

[0019] Different aspects of the invention will no...

Abstract

A backlight unit and a display device having a display panel (40) and a backlight unit that comprises a panel guide mold (10), a bottom cover (20), and a light supply unit (30), where the panel guide mold and the bottom cover are configured to provide sufficient stiffness and structural stability so that the width of the bezel is very small. The panel guide mold comprises a plurality of first mold units (11) and a plurality of second mold units (13), where each of the plurality of second mold units is disposed between two of the first mold units, and the plurality of first mold units are offset in an outward direction relative to the plurality of second mold units. The bottom cover comprises a plurality of first sidewalls (21), each being aligned with a corresponding first mold unit, and a plurality of second sidewalls (23), where each is disposed between two of the first sidewalls and coupled to a corresponding second mold unit.

Description

technical field [0001] The present disclosure relates to a backlight unit and a display device having the backlight unit. Background technique [0002] A liquid crystal display (LCD) device may include a liquid crystal panel for displaying images and a backlight unit disposed on a rear side of the liquid crystal panel to supply light to the liquid crystal panel. The backlight unit may include lamps or light emitting diodes (LEDs) as light sources. [0003] The backlight unit includes a bottom cover, a panel guide module, and a top case. The bottom cover is the basic structure for the assembly of the light source, the optical sheet and the optical subsidiary structure. The bottom cover must be flat and rigid. The panel guide module guides the LCD panel, prevents the optical sheet from sliding, and covers the brightness Mura area. In a large display device with a large-sized liquid crystal panel, the panel guide module is screw-coupled to the bottom cover. Typically, the ...
