Method of manufacturing liquid crystal display device, and system of manufacturing liquid crystal display device

摘要

A method includes the steps of: (a) measuring a height of a pillar spacer after the pillar spacer is formed on a main surface of a CF substrate; (b) measuring a gap between a TFT substrate and the CF substrate after the TFT substrate and the CF substrate are bonded to each other; and (c) determining a quality of a liquid crystal panel based on the difference between the measured height of the pillar spacer and the measured gap.

1. A method of manufacturing a liquid crystal display device having a liquid crystal panel that displays a video image, said liquid crystal panel including:
first and second substrates arranged to be opposite to each other; a pillar spacer arranged on a main surface of said first substrate opposite to said second substrate, the pillar spacer holding a gap between said first substrate and said second substrate; and liquid crystal held between said first and second substrates, a manufacturing method of said liquid crystal panel includes the steps of: (a) measuring a height of said pillar spacer after said pillar spacer is formed on said main surface of said first substrate; (b) measuring the gap between said first and second substrates after said first and second substrates are bonded to each other; and (c) determining a quality of said liquid crystal panel based on a difference between the measured height of said pillar spacer and said measured gap.
