Patent ID: 7522243

Claim:
A display device comprising: a substrate; a circuit element, which is provided on the substrate; an interlayer film, which is provided over the circuit element and which includes an interlevel dielectric layer and an interconnecting member that runs through the interlevel dielectric layer; and an electrode, which is provided on the interlayer film, wherein the electrode and the circuit element are electrically connected together by way of the interconnecting member, wherein the electrode on the interlayer film has a concave-convex surface shape, wherein a surface of the interconnecting member and a surface of the interlevel dielectric layer have a continuous concave-convex shape thereby defining the concave-convex surface shape of the electrode, and wherein the electrode and the interconnecting member are made of different materials; and wherein the electrode has a retro-reflection property, and wherein a retro-reflection property of a concave portion of the electrode on the interconnecting member is substantially the same as that of a concave portion of the electrode on the interlevel dielectric layer.
