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 T, T, and Tof the R emissive layer, the G emissive layer, and the B emissive layer are set to satisfy T<T<T. Due to laser irradiation, the G pixel is selectively annealed at an annealing temperature Tsatisfying T<T<Tto make the R emissive layer of the G pixel lose an emission function. Further, the B pixel is selectively annealed at Tsatisfying T<T<Tto make the R emissive layer and the G emissive layer of the B pixel lose the emission function.
