1. A liquid crystal display device with a touch sensor, comprising:
- a plurality of pixels, each pixel including a thin-film transistor (TFT) and a pixel electrode, the TFT interposed between a lower planarization layer and an upper planarization layer, and the pixel electrode provided on the upper planarization layer;
a touch driver;
a plurality of common signal lines under the lower planarization layer, the plurality of common signal lines connected to the touch driver;
a plurality of bypass lines provided between the lower planarization layer and the upper planarization layer, each of the bypass lines in direct contact with at least one of the common signal lines via a contact hole through the lower planarization layer;
one or more passivation layers provided under the upper planarization layer; and
a common electrode layer on the upper planarization layer, the common electrode layer including separated pieces of common electrode blocks, each of the common electrode blocks connected to at least one of the bypass lines via a contact hole through the upper planarization layer.

Abstract
A display of an electric device includes a plurality of separated transparent electrode blocks, which are configured to provide one or more of supplemental features such as touch recognition. Signal paths between the transparent electrode blocks and the driver for the supplemental feature are implemented with a plurality of conductive lines placed under positioned under one or more planarization layers. The conductive lines implementing the signal paths are routed across the display area, directly toward a non-display area where drive-integrated circuits are located.
