Abstract:
1. A liquid crystal display panel comprising: a first substrate; a second substrate facing the first substrate; a liquid crystal layer provided between the first substrate and the second substrate; an alignment film provided on a side closer to the liquid crystal layer of each of the first and second substrates, and configured to control alignment of the liquid crystal layer; and a sealing member sandwiched between the first substrate and the second substrate, configured to bond the first substrate and the second substrate together, and formed in the shape of a frame surrounding the liquid crystal layer, wherein in a region where the sealing member is to be provided, a metal pattern is provided which is configured to reflect infrared light emitted from a Fourier transform infrared spectrometer toward the Fourier transform infrared spectrometer in order to determine the presence or absence of the alignment film in the region.
