To provide a liquid crystal display device which allows disconnection defects caused in the manufacturing process to be readily repaired with a higher success rate than conventional cases so that the device can be modified into a non-defective device, and a defect repairing method therefor. In one embodiment, the present invention relates to ester compounds that can be used in various personal care formulations andor compounds. The signal processing executing device acquires either the data or the information from the recording device in order to execute the signal processing on the data. The apparatus may also include a reduced-pressure interface for receiving reduced pressure from a reduced-pressure source, and at least one flow channel fluidly coupled to the reduced-pressure interface and the void. A transmitter is configured for transmitting a piece of information representing the capacitive variation, when an absolute value of a difference between the measured capacitance and the reference capacitance exceeds a predetermined threshold.
