Liquid crystal display device and analysis device including the same
First Claim
1. A liquid crystal display device, comprising:
- a liquid crystal display panel which includes a first substrate with a first electrode formed thereon, a second substrate with a common electrode formed thereon and a liquid crystal enclosed between the first substrate and the second substrate, and which displays by changing an orientation of the liquid crystal by a difference in potential applied between the first electrode and the common electrode;
an input and output section which has a first output terminal which sends a signal to the first electrode and a second output terminal which sends a signal to the common electrode configured to drive the liquid crystal display panel;
a control section which uses the first output terminal and the second output terminal of the input and output section as input and output terminals for a defective indication inspection configured to perform an inspection for a defective indication in the liquid crystal display panel, and which performs the inspection for a defective indication by detecting whether a signal sent from one of the input and output terminals of the input and output section can be received at the other of the input and output terminals and performs the inspection for a defective indication every time power is turned on, and/or the display is switched, and stops supply of electric power to the liquid crystal display panel in response to detection of a defective indication;
a sensor section protruding outward in a longitudinal direction from a top end of the liquid crystal display device; and
a sensor located at a distal end of the sensor section connected to the control section configured to contact blood for measurement of blood glucose level in the blood.

Abstract
In order to provide a liquid crystal display device which can detect a defective indication due to short circuit which occurs between a common electrode and a counter electrode by a conductive impurity enters into a liquid crystal display panel, and an analysis device including the same, a blood glucose meter includes a display section and a microcomputer. For performing an inspection for a defective indication on a liquid crystal display panel of the display section, the microcomputer uses ports as input/output ports for a defective indication inspection. The microcomputer detects whether an inspection signal sent from the port can be received at the other port or not to perform the inspection for a defective indication.
