Abstract
A thin film transistor (TFT) is formed on an insulating substrate, and a photosensitive resin film as an interlayer insulating film is formed so as to cover the TFT. Contact holes are formed in the photosensitive resin, and smooth concave and convex portions are provided on an upper surface of the resin. A film including molybdenum nitride (MoN) and a reflective pixel electrode film are successively laminated on the photosensitive resin. The nitrogen content in the MoN film may be between 5 atomic % and 30 atomic % inclusive.
Claims13
A liquid crystal display (LCD) comprising:
- at least one thin film transistor (TFT), an interlayer insulator, and at least one reflective pixel electrode defining at least part of a pixel of the LCD and being supported by a substrate, wherein the interlayer insulator is located at least partially between the reflective pixel electrode and the substrate, and
- a film comprising molybdenum nitride that is immediately below the reflective pixel electrode and contacting the reflective pixel electrode, wherein said film comprising molybdenum nitride is also above the interlayer insulator and contacting the interlayer insulator, so that the film comprising molybdenum nitride is at least partially between the reflective pixel electrode and the interlayer insulator and contacting each of the reflective pixel electrode and the interlayer insulator so that the bottom surface of the film comprising molybdenum nitride is above the top surface of the interlayer insulator and contacting the top surface of the interlayer insulator and the top surface of the film comprising molybdenum nitride is below the reflective pixel electrode and contacting the reflective pixel electrode.
A liquid crystal display comprising:
- a pair of substrates,
- a liquid crystal layer between the pair of substrates,
- a laminated layer provided on at least one of the substrates, wherein the laminated layer comprises an insulating film and a film comprising molybdenum nitride laminated to and over at least part of the insulating film, so that the film comprising molybdenum nitride contacts the upper surface of the insulating film;
- and
- a reflective metal film having a light reflecting function and provided in at least one pixel region of the display for contributing to displaying of images in the display, wherein the reflective metal film is contacts the film comprising molybdenum nitride.
A liquid crystal display (LCD) comprising:
- at least one thin film transistor (TFT),
- an insulating layer at least partially provided over the TFT;
- at least one reflective pixel electrode defining at least part of a pixel of the LCD;
- and
- a film comprising molybdenum nitride in direct contact with the under-side of said reflective pixel electrode, such that the molybdenum nitride of said film comprising molybdenum nitride is in direct contact with both (a) the under-side of the reflective pixel electrode and (b) the upper surface of the insulating layer.
