Abstract: 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.
