Patent ID: 8659710

Claim:
A liquid crystal display device, comprising: a substrate including a display region to display images, the display region including a plurality of touch blocks, each touch block including a plurality of pixel regions; gate and data lines crossing each other on the substrate to define the plurality of pixel regions; a thin film transistor in each pixel region connected to respective ones of the gate and data lines; a blocking pattern below each thin film transistor with a first insulating layer therebetween; a first auxiliary line in each touch block connected to blocking patterns and extending below one of the gate lines with the first insulating layer therebetween; a second auxiliary line in each touch block, each second auxiliary line being located at the same layer as, made of the same material as, and in parallel with the gate lines; a first connection pattern in each touch block contacting respective first and second auxiliary lines; a first passivation layer on the thin film transistor and the first connection pattern; a common electrode in each touch block and on the first passivation layer; x and y sensing lines on the common electrode in each touch block and overlapping the gate and data lines, respectively; a second passivation layer on the x and y sensing lines, and including a drain contact hole in each pixel region to expose a drain electrode of the respective thin film transistor, a first contact hole in each touch block to expose the respective first connection pattern, and a second contact hole in each touch block to expose the respective x sensing line; a pixel electrode in each pixel region, connected to the respective drain electrode through the respective drain contact hole, and including a plurality of openings; and a second connection pattern in each touch block spaced apart from the pixel electrodes, each second connection pattern connected to the respective first connection pattern and the respective x sensing line in each touch block through the first and second contact holes in each touch block, respectively.
