1. A photosensor comprising:

  • a substrate;

    a first electrode layer positioned on the substrate and including a reflection part having an inclination surface, the reflection part reflecting light, and the inclination surface being inclined relative to a surface of the substrate;

    a first semiconductor layer positioned on the first electrode layer;

    a second electrode layer positioned on the first semiconductor layer; and

    a first dielectric layer and a second dielectric layer sequentially positioned on the second electrode layer,wherein the first dielectric layer and the second dielectric layer have different dielectric constant values, andwherein the first dielectric layer has a first dielectric constant value and the second dielectric layer has a second dielectric constant value, and the first dielectric constant value is greater than the second dielectric constant value.
