Abstract
In a display device having driving circuits formed on the same substrate where pixels are formed, the lateral frame area of the display device is reduced. A gate signal line driving circuit is placed in parallel with a source signal line driving circuit, so that no driving circuits are provided in at least two opposing directions out of four directions with respect to a pixel region. With the above-described structure, the area the gate signal line driving circuit occupies in prior art is removed to reduce the width (side to side) of the display device. Therefore a display device that has a small frame area in the lateral direction can be provided.
