Abstract
An electro-optical device includes an element substrate provided with a plurality of pixel electrodes, a counter substrate provided with a common electrode, a liquid crystal sandwiched between the plurality of pixel electrodes and the common electrode, and a dust-proof glass bonded to at least one substrate of the element substrate or the counter substrate and having a heater disposed along an outer side of a display region in plan view.
Claims13
An electro-optical device comprising:
- a first substrate including:
- a scanning line drive circuit disposed along a first direction outside a display region in plan view, and
- a data line drive circuit disposed along a second direction intersecting the first direction outside the display region in plan view;
- a second substrate;
- an electro-optical layer disposed between the first substrate and the second substrate;
- an electrode disposed between the second substrate and the electro-optical layer;
- and
- a third substrate bonded to at least one substrate of the first substrate or the second substrate, the third substrate including a heating member disposed at a position outside the display region and having a light blocking property, wherein
- the heating member overlaps with the scanning line drive circuit, the data line drive circuit, and the electrode in plan view.
