Display device

A display device comprising:

• a display panel;
• a flexible printed circuit board having a connection to the display panel by using a film material;
• a control board having a connection to the flexible printed circuit board by using the film material;
• and
• a semiconductor integrated circuit fixed on the display panel by using the film material and functioning as a drive circuit of the display panel,
• wherein the semiconductor integrated circuit includes a first inspection terminal and a second inspection terminal;
• the display panel, the flexible printed circuit board, and the control board are provided with a first inspection wiring line having one end connected to the first inspection terminal and the other end to which a power supply voltage is applied on the control board, and a second inspection wiring line having one end connected to the second inspection terminal and the other end to which the power supply voltage is applied on the control board;
• and
• the semiconductor integrated circuit includes a first built-in resistor provided between the first inspection terminal and a ground, a second built-in resistor provided between the second inspection terminal and the ground, and an abnormality detection circuit that detects an abnormality in a resistance of the connections using the film material based on an output voltage of a resistance dividing circuit constituted by a resistance of the first inspection wiring line and the first built-in resistor and on an output voltage of a resistance dividing circuit constituted by a resistance of the second inspection wiring line and the second built-in resistor.
