Description

Liquid Crystal Display

The present invention relates to a liquid crystal display device.

Liquid crystal displays are produced by dividing into small modules mounted on mobile phones or digital cameras and large modules mounted on televisions or monitors. Such liquid crystal display devices are classified into light receiving display devices. The liquid crystal display may receive the light emitted from the light source of the backlight unit positioned under the liquid crystal panel to represent an image.

The LCD includes a liquid crystal panel displaying an image and a backlight unit providing light to the liquid crystal panel. The double-sided adhesive tape is included between the liquid crystal panel and the backlight unit. The double-sided adhesive tape not only prevents the separation and separation of the liquid crystal panel but also fixes the guide panel and the optical sheets constituting the backlight unit to prevent the internal parts of the backlight unit from protruding and detaching.

As shown in FIGS. 3 to 6, the liquid crystal display includes a liquid crystal panel 110, optical sheets 120, a battam cover 140, a guide panel 150, a driver 160, and an external substrate 170. And double-sided adhesive tape 130.

The liquid crystal panel 110 displays an image by the driver 160 driving in response to various driving signals supplied through the external substrate 170. The liquid crystal panel 110 includes a liquid crystal layer positioned between the transistor substrate (hereinafter referred to as TFT substrate) 110a and the color filter substrate 110b and includes sub-pixels arranged in a matrix form. A data line, a gate line, a TFT, a storage capacitor, and the like are formed on the TFT substrate 110a, and a black matrix, a color filter, and the like are formed on the color filter substrate 110b. The lower polarizing plate 111a and the upper polarizing plate 111b are attached to the TFT substrate 110a and the color filter substrate 110b constituting the liquid crystal panel 110.

The guide panel 150 (or mold frame) accommodates the light source as well as the optical sheets 120. Typically, the components included in the guide panel 150 and the guide panel 150 are called a backlight unit. The guide panel 150 has a hollow space and a stepped portion 151 that form a rectangular frame shape so that the optical sheets 120 are accommodated therein. In the drawing, only one stepped portion 151 of the guide panel 150 is formed as an example, but may be formed in two or more stages depending on the structure.

The double-sided adhesive tape 130 is attached to the stepped portion 151 of the guide panel 150, and the liquid crystal panel 110 is seated on the double-sided adhesive tape 130. An ear 155 is formed at the stepped portion 151 of the guide panel 150. The ear portion 155 of the guide panel 150 may have a rectangular shape long in the long axis direction.

The ear parts 155 of the guide panel 150 are positioned at one side and the other side of the long axis direction of the guide panel 150, respectively, and they may be formed at positions opposite to each other or at opposite positions. The ear 155 of the guide panel 150 is provided to prevent the flow of the received optical sheets 120. Therefore, the optical sheets 120 are also formed with protrusions (see protrusions 123a of the optical sheet 123 located on the top layer) in the region corresponding to the ear portion 155 of the guide panel 150.

Batam cover 140 is a plate-like support for supporting the lower portion of the guide panel 150. Batam cover 140 is an example that is attached to the lower surface of the guide panel 150 by the adhesive member 141 may be formed integrally with the guide panel 150.

The optical sheets 120 convert a point light source emitted from a light source such as a light emitting diode (LED) into a surface light source, and serve to provide the liquid crystal panel 110. The optical sheets 120 include a light guide plate 121 for converting a point light source emitted from a light source into a surface light source, a light condensing or diffusion sheet 122 for condensing or diffusing a surface light source emitted from the light guide plate 121, and a light condensing or diffusion A protective sheet 123 or the like for protecting the sheet 122 is included. In the case of the optical sheets 120, various sheets may be formed, such as a prism sheet, a lenticular lens sheet, or the like, depending on brightness or other conditions.
