An element substrate of an electro-optical device includes, in a peripheral area surrounding a pixel area, a metal wiring provided at one surface side of a first substrate that is a substrate body, and a plurality of second light-shielding layers overlapping with the metal wiring between the first substrate and the metal wiring. A second light-shielding interlayer area overlapping with the metal wiring is present between the plurality of second light-shielding layers. A third light-shielding layer is formed in a manner overlapping in a plan view with the second light-shielding interlayer area between the first substrate and the metal wiring. Surfaces of the second light-shielding layer and the third light-shielding layer at the first substrate side have lower reflectance than a surface of the metal wiring at the first substrate side.

Electro-optical device and electronic apparatus

An electro-optical device includes a substrate, a first terminal that is formed on the substrate, a second terminal that is formed on the substrate and arranged in a first direction with respect to the first terminal, a third terminal that is formed on the substrate, and arranged in a second direction different from the first direction with respect to the first terminal, and of which the position in the first direction is the same as the first terminal, and a wiring that is formed on the substrate and connected to the third terminal.

A circuit includes a first logic circuit section that outputs a signal that could be in an active voltage level depending on a transfer-signal input from a shift register throughout a display period and outputs a signal whose voltage is constant at the active voltage level throughout an off sequence period; an enable signal output section that outputs an enable signal that is pulsed during the display period; and a second logic circuit section that outputs a signal corresponding to a logical product of the output signal of the first logic circuit section and the enable signal. The enable signal output section keeps the voltage of the enable signal constant at the active voltage level throughout the off sequence period.

An electro-optical device is provided with a data line which are provided in a pixel region, a pixel electrode formed from a transparent conductive material which is upper layer than the data line, a storage capacitance electrode which is provided in a layer between the pixel electrode and the data line so as to face the pixel electrode via a capacitance insulation film, an additional capacitance which has a first capacitance electrode and a second capacitance electrode which is formed in the same layer as the pixel electrode and the storage capacitance electrode, respectively. The second capacitance electrode is electrically connected to the data line.

An electro-optical device includes red, green, and blue sub pixels and red, green, and blue data lines connected to the corresponding sub pixels. Red, green, and blue sampling switches are provided in a peripheral region and are electrically connected to data lines of the corresponding color. The green sampling switch is located at a position that is closer to the pixel region than are the red or blue sampling switches.

An electro-optical device includes three data lines intersecting a scanning line. Three sampling circuits are aligned in a different direction than the direction in which three (R, G, B) sub pixel units are aligned. An image signal line of one sampling circuit extends across the gate electrode of a transistor in another one of the sampling circuits.
