Embodiment Construction

[0042] Hereinafter, when a film (or layer) is formed on (or located on) the "upper" of another film (or layer), it should be understood that the third film (or layer) may exist on the two films (or layer) Between and / or the two films (or layers) may be adjacent to each other.

[0043] figure 1 To illustrate an equivalent circuit diagram of the liquid crystal display device according to the first exemplary embodiment of the present invention. in figure 1 , Two adjacent pixels P1 and P2 in the extending direction of the data lines DL1 and DL2 are shown. The pixels P1 and P2 are each connected to the corresponding gate line GL and each pixel is connected to the data lines DL1 and DL2, and each pixel includes two thin film transistors T1 and T2.

[0044] In the upper pixel P1, the first thin film transistor T1 is connected to the first data line DL1 and the gate line GL, and the second thin film transistor T2 is connected to the second data line DL2 and the gate line GL.

Abstract

An LCD device comprises: a first substrate; a second substrate facing to the first one and comprising a common electrode; and a liquid crystal layer disposed between the first and the second substrates, wherein the first substrate comprising: data lines and grid lines which are intercrossed; and an pixel electrode which bends at least for one time and comprises a first sub-pixel electrode and a second sub-pixel electrode separately, wherein the first sub-pixel electrode extends along the direction of the data lines, the second sub-pixel electrode comprises a first part at right side of the first sub-pixel electrode and a second part at left side of the first sub-pixel electrode, and the data line comprises a first data line passing through the first part and a second data line passing through the second part.

Description

Technical field [0001] The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device having better visibility through improved pixel electrodes. Background technique [0002] The liquid crystal display device includes: a first substrate in which thin film transistors are formed; a second substrate arranged opposite to the first substrate; and a liquid crystal layer interposed between the first substrate and the second substrate. The vertical alignment (VA) mode liquid crystal display device provides an improved viewing angle by using domain division parts formed on the pixel electrode and the common electrode. The fringe field formed by the domain divider is used to control the direction of the liquid crystal molecules so that the viewing angle is improved. [0003] In a conventional vertical alignment (VA) mode device, a shield electrode using a transparent conductive material is formed in the upper part of the data lin...
