Title:
ELECTRO-OPTICAL DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2023040469
Kind Code:
A
Abstract:
To provide an electro-optical device in which the output voltage of a temperature detection circuit is not easily affected by the parasitic capacitance between a temperature detection element and wiring, and an electronic apparatus.SOLUTION: In an electro-optical device 100, on the outside of a display area 10a, a temperature detection element 11 is provided in which a plurality of diodes D are electrically connected in series by relay parts P1, P2. On the outside of the display area 10a, common potential wiring 8a provided with an opening 8a0 is provided, and the temperature detection element 11 is located inside the opening 8a0 in plan view. With this, a parasitic capacitance with a large capacitance is not present between the relay parts P1,P2 and the common potential wiring 8a. On the inside of the opening 8a0 in plan view, an island-like light-shielding layer 8e on the same layer as the common potential wiring 8a is provided separate from the common potential wiring 8a.SELECTED DRAWING: Figure 7
