摘要：
A liquid crystal display panel (1) includes: touch switches (50) each constituted by a switch electrode (52) of an active substrate (12) and a set of switch PS electrodes (51) of a counter substrate (11) so as to make conduct electricity when the active substrate (12) or the counter substrate (11) is pressed; and reflection coatings (38 and 39) which reflect infrared light emitted from a Fourier transform infrared spectrophotometer, the reflection coatings (38 and 39) being provided either in the active substrate (12) or the counter substrate (11) with the switch electrode (52) or the set of switch PS electrodes (51) stacked on a corresponding one of the reflection coatings (38 and 39). This provides a technique for efficiently determining the presence or absence of an alignment film on any touch switch provided inside of a liquid crystal display panel having the function of an in-cell touch sensor.
