The specific embodiment
[the 1st embodiment]
Below, the 1st embodiment that the present invention relates to reference to accompanying drawing explanation.
(organic EL)
Figure 1A is the birds-eye view of the formation of expression organic EL.Figure 1B is the b-b cutaway view among Figure 1A.Fig. 1 C is the c-c cutaway view among Figure 1A.
Shown in Figure 1A~Fig. 1 C, organic EL 50 is on sheet material substrate FB, to have formed gate electrode G and gate insulator I, and then forms after source electrode S, drain electrode D and the pixel electrode P, forms the bottom contact-type of organic semiconductor layer OS.
Shown in Figure 1B, on gate electrode G, be formed with gate insulator I.On gate insulator I, be formed with the source electrode S of source bus line SBL, and be formed with and pixel electrode P bonded assembly drain electrode D.Between source electrode S and drain electrode D, be formed with organic semiconductor layer OS.So far, accomplished FET.In addition, shown in Figure 1B and Fig. 1 C, on pixel electrode P, form luminescent layer IR, on this luminescent layer IR, form transparency electrode ITO.
