The presence or absence of touch is detected according to a difference of a capacitance caused by the presence or absence of a material that blocks the electric field formed between the detection electrode and the common electrode. The common electrode includes a plurality of divided electrode portions that is extended in a lateral direction and aligned with each other in a longitudinal direction. Each of the plurality of common lines is electrically connected to at least one of the divided electrode portions. The plurality of common lines is arranged in an area next to the common electrode in the lateral direction of the common electrode, arranged next to each other in a width direction orthogonal to a length thereof, is different in width from each other, and the width of the common lines is wider as the length is longer.

Display device and liquid crystal display device with built-in touch panel

A display device includes pixel electrodes formed in an image display area of a substrate, a common electrode formed in the image display area, inside signal lines formed inside the image display area, and electrically connected to the pixel electrodes, outside signal lines formed outside the image display area, and electrically connected to the inside signal lines, and a common line formed inside and outside the image display area, and electrically connected to the common electrode. An image is displayed under a control of a light using an electric field developed between the pixel electrodes and the common electrode. A coupling capacitance is formed between the inside signal lines and the common electrode. The outside signal lines each include a first portion, and a second portion higher in electric resistance than the first portion and the inside signal lines.
