LIQUID CRYSTAL DISPLAY AND A METHOD OF MEASURING A CAPACITANCE OF A LIQUID CRYSTAL DISPLAY

摘要

A liquid crystal display including: a display area which includes an upper substrate, a lower substrate, pixels and a liquid crystal layer interposed between the upper and lower substrates; and a measuring unit including a tag portion, a common voltage applying portion, and a pixel voltage applying portion, in which the common voltage applying portion and the tag portion, and the pixel voltage applying portion and the tag portion are connected to each other, a data conductor, a common electrode, a passivation layer, and a pixel electrode are disposed on the common voltage applying portion with substantially the same thickness as at least one of the pixels of the display area, a first part of the data conductor of the common voltage applying portion directly contacts the pixel electrode, and a second part of the data conductor of the common voltage applying portion directly contacts the common electrode.

1. A liquid crystal display, comprising:
a display area which includes an upper substrate, a lower substrate, a plurality of pixels and a liquid crystal layer interposed between the upper substrate and the lower substrate; and a measuring unit including a tag portion, a common voltage applying portion, and a pixel voltage applying portion, wherein the common voltage applying portion and the tag portion are connected to each other, and the pixel voltage applying portion and the tag portion are connected to each other, a data conductor, a common electrode, a passivation layer, and a pixel electrode are disposed on the common voltage applying portion with substantially the same thickness as at least one of the pixels of the display area, a first part of the data conductor of the common voltage applying portion directly contacts the pixel electrode of the common voltage applying portion, and a second part of the data conductor of the common voltage applying portion directly contacts the common electrode of the common voltage applying portion.
