Liquid crystal display device substrate, method of manufacturing liquid crystal display device substrate, liquid crystal display device and method of manufacturing liquid crystal display device

A method of manufacturing a liquid crystal display device comprising the steps of:

• forming a liquid crystal display device substrate so to have an electrode formed to partially cover a main surface and including a linear alignment control protrusion provided on said electrode for controlling alignment of liquid crystal;
• forming an opening in a region of said electrode, the region corresponding to an absent portion occurring on an imaginary line extended from said linear alignment control protrusion;
• and
• completing manufacturing of the liquid crystal display device;
• wherein
• in said step of forming the opening, said opening that is substantially rectangular in shape and that has a length of a shorter side of at least about 3 μm and at most about 20 μm is formed.

A liquid crystal display device substrate comprising:

• a substrate having a main surface;
• a pixel electrode arranged to cover each pixel region defined on said main surface;
• and
• an alignment control protrusion arranged on said pixel electrode so as to control alignment of liquid crystal;
• wherein
• said pixel electrode has an opening;
• at least a portion of said opening is located in a region covered with said alignment control protrusion;
• and
• said alignment control protrusion includes a main alignment control protrusion and an auxiliary alignment control protrusion extending to overlap a side of said pixel electrode, and said opening is provided in a region covered with said auxiliary alignment control protrusion.

A liquid crystal display device substrate comprising:

• a substrate having a main surface;
• a counter electrode located at said main surface;
• a shield layer disposed to define each pixel region at said main surface;
• and
• an alignment control protrusion arranged on said counter electrode so as to control alignment of liquid crystal;
• wherein
• said counter electrode has an opening;
• at least a portion of said opening is located in a region covered with said alignment control protrusion;
• and
• said alignment control protrusion includes a main alignment control protrusion and an auxiliary alignment control protrusion extending to overlap a side of said shield layer, and said opening is provided in a region covered with said auxiliary alignment control protrusion.
