Alignment indicators for liquid crystal display

摘要

Alignment indicators for an LCD device are used for determining misalignment when assembling two LCD substrates together, where a lower substrate includes an array of thin film transistors and an upper substrate includes a color filter array. A first alignment indicator is defined on a first substrate, and a second alignment indicator defined on a second substrate, wherein recessed portions with various depths and protruded portions with various lengths are defined at the outer edges of the second alignment indicator so that the amount of misalignment can be accurately measured by reading the position of the recessed portions and the protruded portions relative to the first alignment indicator when the upper and lower substrates are put together.
