Abstract
An electro-optical device includes a first substrate including a plurality of pixel electrodes, a second substrate having translucency, an electro-optical layer disposed between the first substrate and the second substrate, the electro-optical layer having an optical property that varies in accordance with an electric field generated by the plurality of pixel electrodes, and a spacer disposed between the first substrate and the second substrate, the spacer including a high refractive index portion having a refractive index greater than a refractive index of the electro-optical layer, the spacer being configured to define a distance between the first substrate and the second substrate.
