There is provided an electro-optical device including, above a substrate, data lines extending in a first direction, scanning lines extending in a second direction and intersecting the data lines, pixel electrodes and thin film transistors disposed so as to correspond to intersection regions of the data lines and the scanning lines; and storage capacitors electrically connected to the thin film transistors and the pixel electrodes, the thin film transistors including semiconductor layers having channel regions which extend in a longitudinal direction and channel adjacent regions which extend further from the channel regions in the longitudinal direction, and the scanning lines including light-shielding parts disposed at sides of the channel regions.

Liquid crystal display with capacitive light shield between data line and pixel electrode

An electro-optical device includes: data lines extending in a first direction above a substrate; scanning lines extending in a second direction and intersecting the data lines; pixel electrodes and thin-film transistors arrayed so as to correspond to intersection regions of the data lines and the scanning lines; capacitors formed at a layer higher than the semiconductor layer of the thin-film transistors and at a layer lower than the pixel electrodes, and electrically connected to pixel potential; and upper light shielding film positioned between the data lines and the pixel electrodes; the upper light shielding film defining at least the corners of pixel opening regions; and the scanning lines, the data lines, and the capacitors, being formed in the light shielded region.

Electro-optical device and electronic apparatus

An electro-optical device includes, above a substrate, data lines extending in a first direction, scanning lines which extend in a second direction and which cross the data lines, pixel electrodes and thin film transistors disposed so as to correspond to regions in which the data lines and the scanning lines cross, storage capacitors electrically connected to the thin film transistors and the pixel electrodes, and a shield layer disposed between the data lines and the pixel electrodes. An upper electrode and a lower electrode between which a dielectric film forming each storage capacitor is supported including a first portion laminated along a plane parallel with one surface of the substrate and a second portion laminated along a plane orthogonal to the surface of the substrate, the sectional shape of the capacitor including a projecting shape.

A laser has an active layer formed on a prepared substrate, a cladding layer on the active layer and a contact layer on the cladding layer. The active layer and contact layer are formed of a semiconductor material of elements from Groups III-V. The contact layer and cladding layer are formed into an elongated projecting rib wherein the cladding layer has a remaining planar portion disposed across the active layer. An insulating layer of semiconductor of elements from Group II-VI is formed on each side of the rib supported on the remaining cladding layer.
