ABSTRACT:
A liquid crystal display apparatus includes a first substrate provided with an alignment film on one surface thereof, and a second substrate provided with an alignment film on one surface thereof. The first and second substrates are arranged to oppose each other with the alignment films inside the opposed first and second substrates. Spacers are interposed between the first and second substrates, and pixels are arranged in a matrix in the display apparatus. The spacers are arranged such that, along a direction of rubbing treatment for the alignment film of the second substrate, not more than one spacer is provided per pixel, at least one spacer is present per three consecutive pixels, and no three consecutive pixels all have a respective spacer corresponding thereto.
