    Abstract: An EL display device includes a TFT substrate on which a scanning line extends in a first direction, a video signal line extends in a second direction, and an EL element having an anode, a luminous layer and a cathode. A protective film covers the scanning line, the video signal line and the EL element. A touch panel detection electrode is disposed above the protective film, and connected to a wiring which is disposed under the protective film via a through hole of the protective film. The touch panel detection electrode has an angle to intersect with the video signal line.

    Abstract: The invention allows formation of LTPS TFTs and TAOS TFTs on the same substrate. The invention provides a display device including a substrate having a display area in which pixels are formed. The pixels include a first TFT made of a TAOS. The drain of the first TFT is formed of first LTPS 112. The source of the first TFT is formed of second LTPS 113. The first LTPS 112 is connected to a first electrode 106 via a first through-hole 108 formed in an insulating film 105 covering the first TFT. The second LTPS 113 is connected to a second electrode 107 via a second through-hole 108 formed in the insulating film 105 covering the first TFT.
