Abstract
A display device includes a substrate, a circuit element, an interlayer film, and an electrode. The circuit element is provided on the substrate. The interlayer film is provided over the circuit element and includes an interlevel dielectric layer and an interconnecting member that runs through the interlevel dielectric layer. The electrode is provided on the interlayer film. The electrode and the circuit element are electrically connected together by way of the interconnecting member. The electrode on the interlayer film has a substantially uniform surface shape.
Claims26
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, and
- wherein the electrode on the interlayer film has a substantially uniform surface shape.
A method for fabricating a display device, the display device including:
- a substrate;
- a circuit element 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 on the interlayer film, the electrode and the circuit element being electrically connected together by way of the interconnecting member, the method comprising the steps of:
- (a) forming the interlayer film that includes the interlevel dielectric layer and the interconnecting member running through the interlevel dielectric layer;
- (b) changing the surface shape of a portion of the interlayer film, on which the electrode will be provided, into a predetermined shape after the step (a) has been performed;
- and
- (c) forming the electrode on the interlayer film.
