Patent ID: 8582064

Claim:
An MVA type liquid crystal display device comprising a plurality of pixels arranged in a matrix of rows and columns, each of said plurality of pixels comprising: a first substrate; a second substrate; a vertical alignment type liquid crystal layer sandwiched between said first substrate and said second substrate; at least one first electrode formed on said first substrate; a second electrode facing said at least one first electrode through said liquid crystal layer; a first domain control structure formed on said first substrate; and a second domain control structure formed on said second substrate, wherein said first domain control structure is a slit formed in said at least one first electrode, and said second domain control structure is a slit formed in said second electrode or a dielectric protrusion formed on said second electrode on a side facing said liquid crystal layer, wherein, when observed from a direction vertical to said first substrate, said first domain control structure includes a first linear component extending in a first direction and a second linear component extending in a second direction which is about 90° angled from said first direction, and said second domain control structure includes a third linear component extending in said first direction and a fourth linear component extending in said second direction, wherein at least either said first and second linear components or said third and fourth linear components are present in plurality, wherein said first linear component and said third linear component are arranged alternately, and said second linear component and said fourth linear component are arranged alternately when observed from a direction vertical to said first substrate, wherein when a voltage is applied to said liquid crystal layer at a given pixel of said plurality of pixels, four domains that differ in directions in which liquid crystal molecules fall by about 90° from one another are formed between said first linear component and said third linear component and between said second linear component and said fourth linear component, wherein each of said plurality of pixels is a horizontally long pixel whose side extending in a row direction is longer than the side extending in a column direction, and wherein said at least one first electrode includes two first electrodes disposed side by side along the row direction.
