Abstract:
1. A method of forming a transflective liquid crystal display device with a wide-viewing angle, comprising the steps of: providing a first substrate and a second substrate opposite the first substrate; forming an insulating layer having an uneven first surface, and a second surface opposite the first surface, the second surface on the first substrate; etching only partially through the insulating layer from the first surface to form at least one opening in the insulating layer, the opening having a bottom surface in the insulating layer spaced above the second surface; forming a conformal transparent electrode on a sidewall and a bottom of the opening and a reflective electrode on part of the insulating layer, wherein the sidewall and bottom of the opening are covered only by the transparent electrode; forming a conformal first alignment film on the reflective electrode; forming a common electrode on an inner surface of the second substrate; forming a second alignment film on the common electrode; and filling a space between the first substrate and the second substrate with negative type liquid crystal molecules added with a chiral agent to form a liquid crystal layer.
