1. An electro-optical device, comprising:

  • 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 the 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, wherein each of the plurality of pixel apertures is formed so as to penetrate the lyophilic layer and the lyophobic layer, wherein the lyophobic layer has relatively weak affinity for a material solution used for forming the injection layer in comparison with the lyophilic layer and includes a plurality of lyophilic portions corresponding to the plurality of pixel apertures, and wherein the plurality of lyophilic portions are provided so as to be separate from each other, wherein each of the plurality of the lyophobic portions surrounds the corresponding pixel aperture of the plurality of pixel apertures.
