Abstract
An AMLCD having high fineness and high contrast is realized. First, an interlayer film is provided on an element electrode, and an opening portion is formed in the interlayer film. Next, after a first metal layer is formed, an embedded insulating layer is formed. The embedded insulating layer is retreated by a means, such as an etch back method, to realize a state in which only the opening portion is filled with the embedded insulating layer. By this, electric connection between the element electrode and a second metal layer becomes possible while keeping the flatness.
Claims21
A display device comprising a pixel matrix circuit comprising a plurality of pixels each including at least one TFT and a pixel electrode connected to the TFT,
- wherein the pixel electrode includes a lamination structure of a first metal layer and a second metal layer;
- wherein the first metal layer is in contact with the second metal layer,
- an insulating layer is put between the first metal layer and the second metal layer at a contact portion where the first metal layer is connected with the TFT, and
- wherein the insulating layer comprises a light absorbing layer comprising a resin in which a pigment or a carbon-based material is contained.
A display device comprising a pixel matrix circuit comprising:
- a TFT;
- a first insulating layer over the TFT, wherein the first insulating layer comprises a contact hole;
- a first conductive film over the first insulating film and in the contact hole, wherein the first conductive film is electrically connected to the TFT through the contact hole;
- a second insulating layer filled in the contact hole, wherein an upper surface of the first conductive film outside the contact hole is not covered by the second insulating layer;
- a second conductive film on and in contact with the upper surface of the first conductive film and the second insulating layer,
- wherein the second insulating layer comprises a light absorbing layer comprising a resin in which a pigment or a carbon-based material is contained.
