Abstract
An electro-optical device includes a substrate, a first electrode, a second electrode, a third electrode, a first reflection layer, a second reflection layer, a light emission function layer, a first optical adjustment layer, a second optical adjustment layer, a first driving circuit, a second driving circuit, a first conductive portion being in contact with the second electrode at a first position in a normal line direction of the substrate and being configured to electrically couple the second electrode and the first reflection layer, and a second conductive portion being in contact with the third electrode at a second position in the normal line direction and being configured to electrically couple the third electrode and the second reflection layer.
Claims8
An electro-optical device comprising:
- a substrate;
- a first electrode having a semi-transmissive property;
- a second electrode having a light transmissive property, being provided between the first electrode and the substrate, and facing the first electrode;
- a third electrode having a light transmissive property, being provided between the first electrode and the substrate, and facing the first electrode;
- a first reflection layer being provided between the substrate and the second electrode and facing the second electrode;
- a second reflection layer being provided between the substrate and the third electrode and facing the third electrode;
- a light emission function layer being provided between the first electrode and the second electrode and between the first electrode and the third electrode;
- a first optical adjustment layer being provided between the second electrode and the first reflection layer;
- a second optical adjustment layer being provided between the third electrode and the second reflection layer;
- a first driving circuit being provided at the substrate and being configured to control a current amount supplied to the second electrode;
- a second driving circuit being provided at the substrate and being configured to control a current amount supplied to the third electrode;
- a first conductive portion being in contact with the second electrode at a first position of the substrate in a normal line direction and being configured to electrically couple the second electrode and the first reflection layer;
- and
- a second conductive portion being in contact with the third electrode at a second position in the normal line direction and being configured to electrically couple the third electrode and the second reflection layer, wherein
- the second electrode includes a first light emission region through which light in a first wavelength range passes,
- the third electrode includes a second light emission region through which light in a second wavelength range passes,
- a first distance is larger than a second distance, and a difference between a third distance and a fourth distance is smaller than a difference between the first distance and the second distance, the first distance being a distance between the first light emission region of the second electrode and the first reflection layer in the normal line direction, the second distance being a distance between the second light emission region of the third electrode and the second reflection layer in the normal line direction, the third distance being a distance between the first reflection layer and the first position in the normal line direction, the fourth distance being a distance between the second reflection layer and the second position in the normal line direction.
