In a manufacturing method of a color liquid crystal display device, a first conductive film is formed on a transparent insulating substrate to form a gate electrode and a gate bus line. The invention thus relates to the plants, seeds and tissue cultures of the variety CV927887, and to methods for producing a corn plant produced by crossing a corn plant of variety CV927887 with itself or with another corn plant, such as a plant of another variety. The primary clearance surface defines a first acute relief angle, the secondary clearance surface defines a second acute relief angle less than the first acute relief angle, and the tertiary clearance surface defines a tertiary acute relief angle greater than the first and second relief angles.
