1. A display panel, comprising:
- a first optically transparent electrode layer;
a second optically transparent electrode layer;
a conductivity-variable layer provided on the first optically transparent electrode layer; and
an electroluminescent layer provided between the conductivity-variable layer and the second optically transparent electrode layer, which emits light by applying a voltage thereto;
a predetermined voltage being applied between the first optically transparent electrode layer and the second optically transparent electrode layer, and the conductivity-variable layer having its electrical conductivity changed in accordance with a light quantity of control light transmitted through the first optically transparent electrode layer; and
the electroluminescent layer emitting the light so that the voltage in the predetermined voltage as corresponds to the conductivity of the conductivity-variable layer, is applied thereto when the conductivity of the conductivity-variable layer has been changed in accordance with the light quantity of the control light transmitted through the first optically transparent electrode layer.
