Patent ID: 8842244

Claim:
A character type vertical alignment mode liquid crystal display device comprising: first and second substrates opposing each other; a first electrode layer including a plurality of first electrodes provided at an inner side of said first substrate; a second electrode layer including a plurality of second electrodes provided at an inner side of said second substrate; first and second vertical alignment layers provided between said first and second substrates to cover said first and second electrode layers, respectively, said first and second vertical alignment layers being subject to an alignment process from at least one side of said first and second vertical alignment layers; a mono-domain type vertical alignment mode liquid crystal layer provided between said first and second substrates, one of said first and second alignment layers giving a pretilt angle in liquid crystal modules in said mono-domain type vertical alignment mode liquid crystal layer; and a wall structure provided between said first and second substrates; wherein said wall structure comprises wall layers each with a shape along a periphery of one of display patterns formed by superposing said segment electrodes onto said common electrodes; and wherein a height of said wall structure is not smaller than half of a height of said mono-domain type vertical alignment mode liquid crystal layer.
