PROBLEM TO BE SOLVED: To suppress changes in the electrical characteristics of a display device including transistors in a pixel region and a drive circuit region and improve reliability of the display device.SOLUTION: A display device includes: a first substrate 102 in which a drive circuit region that is located outside and adjacent to a pixel region 142 and includes at least one second transistor 103 which supplies a signal to a first transistor 101 included in each of the pixels in the pixel region, is formed; a second substrate 152 provided to face the first substrate; and a liquid crystal layer held between the first substrate 102 and the second substrate 152, and includes: a first interlayer insulating film formed of an inorganic insulating material over the first transistor 101 and the second transistor 103; a second interlayer insulating film formed of an organic insulating material over the first interlayer insulating film, and a third interlayer insulating film formed of an inorganic insulating material over the second interlayer insulating film. In the display device, the third interlayer insulating film is provided on part of the pixel region 142, and an edge portion of the third interlayer insulating film is formed on an inner side than the driver circuit region.SELECTED DRAWING: Figure 1 |
