Each pixel may include a thin film transistor (not shown) connected to a gate line and a data line, a pixel electrode connected to the thin film transistor, and a common electrode formed adjacent to the pixel electrode and supplied with a common voltage. At this time, the common electrode may be formed on the lower substrate 114 according to the driving method of the liquid crystal layer. The upper substrate 112 forms an electric field corresponding to a difference voltage between a data voltage and a common voltage applied to each pixel to control the light transmittance of color light transmitted through the lower substrate 112 and the liquid crystal layer, So that a predetermined color image is displayed.

On both sides of the upper substrate 112, a gate driving circuit (not shown) connected to the gate line by the thin film transistor manufacturing process is formed. Such a gate driving circuit drives a gate line in response to a gate control signal provided from an external timing control section.

A pad portion PP is provided on the upper portion of the upper substrate 112 with respect to a vertical direction of the display panel 110 erected vertically, to which various signals for driving each pixel are supplied. A panel driving unit 130 for driving the display panel 110 is connected to the pad unit PP.

The panel driving part 130 includes a plurality of circuit films 132 connected to the pad part PP and a printed circuit board 134 connected to the plurality of circuit films 132. [

Each of the plurality of circuit films 132 includes a data driving integrated circuit 136 for supplying a data signal to a data line formed on the upper substrate 112. The plurality of circuit films 132 are attached to the pad portion PP and the printed circuit board 134 by a TAB (Tape Automated Bonding) process and are formed of a tape carrier package (TCP) or a chip on flexible board (COF) On Film). Accordingly, the display panel 110 is electrically connected to the printed circuit board 134 through the plurality of circuit films 132. [

The printed circuit board 134 is electrically connected to the plurality of circuit films 132 to provide various signals for displaying an image on the display panel 110.

The lower substrate 114 includes a horizontal and vertical shielding layer (not shown) for defining a pixel region corresponding to each pixel formed on the upper substrate 112, an edge shielding layer (not shown) formed at the edge of the lower substrate 114 And a color filter (not shown) formed in each pixel region. The color filter is made to pass through the lower substrate 114 from the backlight unit 140, and filters the light traveling toward the upper substrate 112 with predetermined color light. A common electrode (not shown) to which a common voltage is supplied may be formed on the lower substrate 114 according to the driving method of the liquid crystal layer.

A specific configuration of the upper substrate 112 and the lower substrate 114 may be a driving mode of the liquid crystal layer, for example, a TN (Twisted Nematic) mode, VA (Vertical Alignment) A Fringe field switching (FFS) mode, and the like.

For example, the stereoscopic optical member 116b may be a retarder film for separating a two-dimensional image, that is, a left-eye image and / or a right-eye image into different polarized states.

All the signal lines formed on the upper substrate 112 of the display panel 110 are not exposed to the outside but are made of a metal material so that external light transmitted through the upper substrate 112 can be reflected to the outside. Thus, a signal line or the like formed on the upper substrate 112 from the outside of the display panel 110 can be seen. In order to prevent this, the display panel 110 includes an upper substrate 112, an upper polarizing film 116, 116a (see FIG. 4A) Or a light blocking pattern 112a formed on the upper surface of the optical member for stereoscopic image 116b and blocking external light incident on a signal line formed on the upper substrate 112.

[ At this time, the additional information may be a manufacturer logo of a display device, an advertisement, caption information of a moving picture, volume information, channel information, and time information.

On the other hand, each pixel of the auxiliary display region 102b may be formed to have a different size from each pixel of the main display region 102a. For example, since the auxiliary display area 102b displays the additional information, a high resolution is not required unlike the main display area 102a. Therefore, each pixel of the auxiliary display area 102b is divided into the main display area 102a, May be formed to have a size at least three times larger than that of each pixel. To this end, the size of each pixel of the auxiliary display area 102b is preferably increased in the longitudinal direction of the data line.

The peripheral portion 104 is formed at a rim portion of the display panel 110 to define the display portion 102 and surrounds the display portion 102. [ The upper part of the peripheral part 104 surrounding the upper part of the main display area 102a is overlapped with the pad part PP provided on the upper substrate 112 so that the panel driving part 130 is moved to the outside of the display panel 110 Thereby preventing reflection.

Accordingly, the display panel 110 has a vertically symmetrical structure with respect to the non-spherical main display region 102a of the auxiliary display region 102b and a peripheral portion 104 having a horizontally symmetrical structure. That is, since the colors of the lower side of the peripheral portion 104 and the auxiliary display region 102b that is not driven are the same, the peripheral portion 104 including the auxiliary display region 102b has the same width .
