Abstract
An electro-optical device includes a substrate having a plurality of pixel electrodes thereon, a bank structure formed on the substrate and provided with a plurality of pixel apertures corresponding to the plurality of pixel electrodes, an injection layer formed in each of the plurality of pixel apertures for injecting electrons or holes, an organic semiconductor layer formed on the injection layer in each of a plurality of pixel apertures; and an electrode formed on the organic semiconductor layer, wherein the individual bank includes a lyophilic layer formed on the substrate and a lyophobic layer formed on the lyophilic layer. Here, each of the plurality of the pixel apertures is formed so as to penetrate the lyophilic layer and the lyophobic layer.
