A display panel comprises a plurality of arranged pixels of organic EL devices, each having a pair of electrodes and a luminescent layer containing an organic EL material and sandwiched between the electrodes. The plurality of arranged pixels include fluorescent pixels of organic EL devices formed by mainly using a fluorescent material and phosphorescent pixels of organic EL devices formed by mainly using a phosphorescent material. A display apparatus comprises a controller for controlling the display panel, including correcting the difference between the electroluminescent characteristics of the fluorescent pixels and those of the phosphorescent pixels.
