Abstract
A display device, with a pair of substrates provided so as to face each other with a display medium interposed therebetween, includes, on a first substrate of the pair of substrates: switching elements disposed in a matrix; scanning lines and signal lines disposed so as to cross each other; and an interlayer insulating film provided so as to have the switching elements, the scanning lines and the signal lines on one surface thereof and pixel electrodes on the other surface thereof. Each of the pixel electrodes is electrically connected to a drain electrode of one of the switching elements via a contact hole which penetrates through the interlayer insulating film. The interlayer insulating film is made of an organic thin film having a high transparency and covers at least the switching elements, the scanning lines and the signal lines. Furthermore, the interlayer insulating film is provided so as to contact directly with the first substrate in a light-transmitting area which is not shaded at least by the switching elements, the scanning lines and the signal lines.
