LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

摘要

A display device may include a substrate and a first roof layer portion that is formed of a roof layer material and overlaps the substrate in a direction, the direction is perpendicular to a surface of the substrate. A lateral surface of the first roof layer portion is disposed in a plane. The display device may further a second roof layer portion formed of the roof layer material and separated from the first roof layer portion. The display device may further a common electrode portion disposed between the first roof layer portion and the substrate in the direction. A lateral surface of the common electrode portion is disposed in the plane or is spaced from the lateral surface of the first roof layer portion in a second direction parallel to the surface of the substrate. The display device may further a pixel electrode disposed between the first common electrode portion and the substrate.

主权项

1. A method for manufacturing a display device, the method comprising:
forming a first pixel electrode and a second pixel electrode that overlap a substrate in a first direction, the first direction being perpendicular to a surface of the substrate; forming a common electrode material layer that overlaps the first pixel electrode and the second pixel electrode; forming a roof layer material layer that overlaps the common electrode material layer; removing a portion of the roof layer material layer to form a first roof layer portion and a second roof layer portion, the first roof layer portion overlapping the first pixel electrode, the second roof layer portion overlapping the second pixel electrode, a lateral surface of the first roof layer portion being disposed in a first plane; and removing a portion of the common electrode material layer to form a first common electrode portion and a second common electrode portion, the first common electrode portion being disposed between the first roof layer portion and the first pixel electrode, the second common electrode portion being disposed between the second roof layer portion and the second pixel electrode, a lateral surface of the first common electrode portion being disposed in the first plane or being spaced from the lateral surface of the first roof layer portion in a second direction parallel to the surface of the substrate.
