Problems solved by technology

[0006] When the light-incident surface of the LGP receives heat, the LGP easily becomes bent or twisted so that the alignment between the light-emitting element and the LGP deviates
Therefore, light incident efficiency decreases and light leaks
[0007] As described above, as the elements of LCD devices become thinner, their reliability decreases, resulting in lower display quality and display efficiency of LCD devices
Also, due to heat applied to the LGP, the LGP tends to become bent or twisted, so that the display quality and display efficiency of the LCD are degraded

Embodiment Construction

[0033] Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. However, the teachings of the present invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the teachings of the present invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0034] It will be understood that when an element or layer is referred to as being "on", "connected to" or "coupled to" another element When another element or layer is present, it can be directly on, connected to or joined to another element or layer, or intervening elements or layers may be present. Conversely, when an element i...

Abstract

A display device includes a light source assembly, a light guide plate (LGP), a lower receiving container, a reinforcing member, a display panel and an upper receiving container. The lower receiving container includes a first coupling portion formed on the first bottom surface. The reinforcing member includes a pressing down part structured to pressing down on an upper surface adjacent to a corner portion of the LGP and a fixing part integrally extending from an end portion of the pressing down part in parallel with a first sidewall of the lower receiving container to have a second coupling portion being coupled with the first coupling portion. The reinforcing member covers the light source assembly. The display panel is disposed on the LGP and the reinforcing member. The upper receiving container includes a third coupling portion coupled to the first coupling portion and the second coupling portion through a coupling member.

Description

technical field [0001] The present invention relates to display devices. More particularly, the present disclosure relates to thin display devices with enhanced strength. Background technique [0002] Liquid crystal display (LCD) devices have many advantages over cathode ray tubes (also referred to as CRTs), for example, they have excellent display quality, small size, light weight, thin thickness, low power consumption, and the like. Accordingly, LCD devices have been used in various fields. [0003] Recently, since the size of the display area of ​​the LCD device increases and the panel thickness of the LCD device decreases according to market demand, the thickness of an optical element such as a light guide plate (LGP) and the thicknesses of an upper storage container and a lower storage container employed in the LCD device have changed. become thinner and thinner. [0004] However, when the thickness of the element employed in the LCD device is very thin, the element ...
