Abstract
The invention provides an electro-optical device in which a voltage drop due to the wiring resistance of a cathode is reduced and therefore steady image signals are transmitted such that erroneous image display, such as low contrast, is reduced or prevented. The invention also provides an electronic apparatus including such an electro-optical device. An electro-optical device includes red, green, and blue luminescent power-supply lines to apply currents to light-emitting elements arranged in an actual display region in a matrix; and a cathode line disposed between the light-emitting elements and a cathode. The cathode line has a width larger than a width of red, green, and blue luminescent power-supply lines.
Claims18
An electro-optical device comprising:
- a substrate having sides at a periphery thereof;
- first electrodes provided in an effective region of the substrate;
- a second electrode opposing the first electrodes;
- a light-emitting layer interposed between the opposing one of the first electrodes and the second electrode;
- a first wiring line electrically coupled to the one of the first electrodes, the first wiring line extending to follow at least one of the sides and including a first portion provided between the effective region and the at least one of the sides;
- and
- a second wiring line electrically coupled to the second electrode, the second wiring line extending to follow at least three of the sides and including a second portion provided between the effective region and the at least three of the sides, the second portion of the second wiring line being formed from the same layer as the first portion of the first wiring line and having a larger area than an area of the first portion of the first wiring line.
