Abstract
A method of forming embossing patterns includes forming a metal layer over a substrate, irradiating a laser beam on the metal layer by using a laser apparatus including an optical scanner, and patterning the metal layer by controlling a scan speed of the optical scanner, thereby forming embossing patterns. The inventive embossing patterns can be formed without using a photoresist patterning step.
Claims17
A method of forming embossing patterns, comprising:
- forming a metal layer over a substrate;
- irradiating a laser beam at the metal layer by using a laser apparatus including an optical scanner;
- and
- patterning the metal layer by controlling a scan speed of the optical scanner, thereby forming embossing patterns.
1 more element
A liquid crystal display device, comprising:
- a first substrate and a second substrate spaced apart from and facing into each other;
- a pixel electrode over an inner surface of the first substrate, a top surface of the pixel electrode having metal embossing patterns, a bottom surface of the pixel electrode being flat;
- a common electrode on an inner surface of the second substrate;
- and
- a liquid crystal layer interposed between the first and second substrates.
