Abstract
Exemplary embodiments of the present invention provide a display panel or the like in which it is easy to enlarge a size of the display panel. A display panel according to exemplary embodiments includes a first transparent electrode layer and a second transparent electrode layer which are optically transparent, a conductivity-variable layer which is provided on the first transparent electrode layer, and an electroluminescent layer which is provided between the conductivity-variable layer and the second transparent electrode layer, and which emits light by applying a voltage thereto.
Claims12
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.
