Problems solved by technology

[0005] The existing BLU is used to make the brightness of light uniform and improve the light efficiency. It is connected to the above-mentioned prism sheet together with the above-mentioned diffusion sheet. Since the additional diffusion sheet and prism sheet increase the number of parts, it is not easy to install the BLU. Lighter, thinner and smaller, but also increase the assembly process, and at the same time, there are problems of increased scrap rate and increased production cost
[0006] However, considering that the backlight unit is the element that has the greatest influence on the overall thickness of a liquid crystal display device that achieves high brightness, for the backlight unit according to Korean Laid-Open Patent No. 2008-0004135, there are many constituent elements that hinder the liquid crystal display device. Thinning and lightweighting issues

Abstract

The present invention relates to a backlight unit and a display device comprising the backlight unit.

Description

technical field [0001] The present application relates to a backlight unit and a display device including the above-mentioned backlight unit. Background technique [0002] Recently, with the development of various portable electronic devices such as mobile phones, PDAs, and notebook computers, the demand for flat panel display devices (flat panel display devices) that can be applied to these devices is gradually increasing. Increase. Researches on LCD (liquid crystal display), PDP (plasma display panel), FED (field emission display), VFD (vacuum fluorescent display) etc. as such flat panel display devices are very active. Liquid crystal display devices (LCDs) are particularly attracting attention due to reasons such as performance, realization of high image quality, and realization of large-size screens. [0003] The above-mentioned liquid crystal display device displays images by using liquid crystal interposed between two electrodes. However, liquid crystals constitutin...
