Display panel, method of manufacturing display panel, and display apparatus

摘要

The invention seeks to provide a display panel or the like which is easy of enlarging a size thereof. A display panel comprising a first transparent electrode layer 102 and a second transparent electrode layer 104 which are optically transparent, a conductivity-variable layer 103 which is provided on the first transparent electrode layer 102, and an electroluminescent layer 110 which is provided between the conductivity-variable layer 103 and the second transparent electrode layer 104, and which emits light by applying a voltage thereto, wherein a predetermined voltage is applied between the first transparent electrode layer 102 and the second transparent electrode layer 104, the conductivity-variable layer 103 has its electrical conductivity changed in accordance with the light quantity of control light L transmitted through the first transparent electrode layer 102, and the electroluminescent layer 110 emits the light in such a way that the voltage in the predetermined voltage as corresponds to the conductivity of the conductivity-variable layer 103 is applied thereto when the conductivity of the conductivity-variable layer 103 has been changed in accordance with the light quantity of the control light L transmitted through the first transparent electrode layer 102.
