Embodiment Construction

[0032] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0033] image 3 shows a plan view of an array test substrate having a plurality of array units according to the present invention, Figure 4 Shown is an enlarged plan view of the first array unit and the second and third array units adjacent thereto according to the present invention. exist Figure 4 In , the letter in the reference symbol of each item or part indicates its associated array element. E.g, Figure 4 A first array unit A100, a second array unit B100 and a third array unit C100 are shown. Where possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0034] Such as image 3 with 4 As shown, the substrate used in LCD according to the present invention includes a plurality of array units 100, a plurality of test pads 150 respectively corresponding to ea...

Abstract

A substrate has an array testing system for use in a liquid crystal display device. The substrate includes a plurality of array cells each including a display area, a non-display area surrounding the display area, and a pad area adjacent to first and second sides of the non-display area. The substrate further includes a plurality of test pads outside the plurality of array cells and a plurality of test lines each connecting a corresponding one of the array cells with a corresponding one of the test pads. Here, each one of the test lines partially pass through the non-display area of an array cell adjacent to the corresponding one of the array cells.

Description

technical field [0001] The present invention relates to an array substrate used in a liquid crystal display device, and more particularly, to an array substrate with a plurality of units and an array testing system embedded thereon. Background technique [0002] Liquid crystal display devices generate images using optical anisotropy and polarization characteristics of liquid crystal molecules. Liquid crystal molecules have a definite alignment due to their elongated shape. Alignment orientation can be controlled by an applied electric field. Therefore, the alignment of liquid crystal molecules can be changed by changing the applied electric field. Due to the optical anisotropy of the liquid crystal molecules, the refraction of incident light depends on the orientation of the aligned liquid crystal molecules. Accordingly, a liquid crystal display device can generate images by controlling an electric field applied to liquid crystal molecules. [0003] Liquid crystal displa...
