Abstract:
Increase in resolution of an organic EL display panel is made achievable with a relatively simple process. An emissive layer of an OLED is formed by stacking an R emissive layer, a G emissive layer, and a B emissive layer corresponding to an R color, a G color, and a B color. The glass-transition temperatures Tg-R, Tg-G, and Tg-B of the R emissive layer, the G emissive layer, and the B emissive layer are set to satisfy Tg-R
