Abstract: A display device includes: a plurality of first electrode patterns; a plurality of second electrode patterns; a plurality of first touch signal lines; and a plurality of second touch signal lines. The plurality of first electrode patterns respectively include a plurality of first electrode cells physically separated from each other and arranged in a first direction. The plurality of second electrode patterns include a plurality of second electrode cells physically separated from each other and arranged in a second direction crossing the first direction. The plurality of first touch signal lines are connected to the first electrode cells. The plurality of second touch signal lines are connected to the second electrode cells. The first and second electrode patterns and the first and second touch signal lines are all positioned at the same layer on a substrate. The first touch signal lines are independently connected to each first electrode cell.

Abstract: A thin film transistor array panel and a manufacturing method capable of forming an insulating layer made of different materials for a portion contacting an oxide semiconductor and a second portion without an additional process. Source and drain electrodes of the thin film transistor each include a lower layer and an upper layer. A first passivation layer contacts the lower layer of the source and drain electrodes but does not contact the upper layer of the source and drain electrodes, and a second passivation layer is disposed on the upper layer of the source and drain electrodes. The first passivation layer may be made of silicon oxide, and the second passivation may be made of silicon nitride.
