Abstract: An object of the present invention is to provide a driver IC and a liquid crystal display apparatus which uses a circuit of an output channel which is not used to drive a liquid crystal panel as a backup of the other output channel. A driver IC includes a plurality of output channels ch1 to chn, a plurality of output buffer circuits corresponding to each of the plurality of output channels ch1 to chn, and an output channel selection circuit, and when a malfunction occurs in the output buffer circuit of an effective channel, the output buffer circuit in which the malfunction occurs is automatically switched to the output buffer circuit of an ineffective channel so that the output of the signal from the effective channel is continued.

Abstract: An electro-optical apparatus includes an electro-optical panel having a first end portion, a first connector that is flexible, and a reinforcement member on the first connector. The first connector has a second end portion and a third end portion opposite to the second end portion. The second end portion is connected to the first end portion. The first connector has a first surface connected to the electro-optical panel, and a second surface opposite to the first surface. The reinforcement member is located on the first surface, and extends from an end surface at the first end portion of the electro-optical panel to the third end portion. The first connector has first and second side edges, at least one of which has a first cutout depressed inward. The first and second side edges connect the second and third end portions to each other.

Abstract: A gate driver IC includes a first diode, a second diode, a first comparator, a second comparator, and a judgement circuit. The first comparator compares a first potential difference between both ends of the first diode and a first threshold. The second comparator compares a second potential difference between both ends of the second diode and a second threshold. Based on comparison results of the first comparator and the second comparator, the judgement circuit determines occurrence of disconnection.

Abstract: In the case that a first scanning line having a smaller number of pixels to be driven than that of a second scanning line in a display device having a heteromorphic display region, capacitance is added to an extended scanning line in which the first scanning line extends to an outside of the display region. A large difference in RC delay between scanning lines generated by the number of pixels to be driven can be compensated for by adding the capacitance, so that luminance unevenness can be prevented to contribute to improvement of display quality.

Abstract: This liquid crystal display device has a first substrate, a second substrate, a liquid crystal layer sandwiched between the first and second substrates, a seal, and a spacer. The seal includes: a first seal part having a linear shape in a first direction; a second seal part having a linear shape in a second direction; and a third seal part having a curved shape that smoothly connects the first seal part and the second seal part. When a second region is a region surrounded by the outer periphery of a first region for displaying an image, the third seal part, a first normal line that extends downward from the boundary point between the first seal part and the third seal part to the outer periphery of the first region, and a second normal line that extends downward from the boundary point between the second seal part and the third seal part to the outer periphery of the first region, and a third region is a region other than the first region and the second region, the spacer arrangement density is greater in the second region than in the third region.
