  • Patent number: 10761384
    Abstract: On the first side substrate of an electro-optical device, a first maintenance capacitance is formed by a first capacitance electrode, a first dielectric layer, and a second capacitance electrode overlapped with each other on a bottom and an inner walls of a first recess section formed in an inter-layer insulation film. The inter-layer insulation film needs to be thick and thus an inter-layer insulation film needs to be thin. A first capacitance line is formed on a surface of the inter-layer insulation film on the side of a pixel electrode. Thus, the first capacitance line shields a section between a gate electrode and the second capacitance electrode to which a drain potential is applied.
