Abstract: A liquid crystal display device includes: common electrodes that are opposed to pixel electrodes respectively; a detection circuit that detects a waveform of a common potential at the plurality of common electrodes; and a determination circuit that determines abnormality of the liquid crystal display device based on the waveform detected by the detection circuit. A plurality of pixels are divided into a plurality of segments, the common electrodes are provided corresponding to the plurality of segments, and the detection circuit detects the waveform of the common potential at each of the common electrodes when a predetermined data signal is input to at least one of data signal lines whiled a predetermined gate signal is input to at least one of gate signal lines.

Abstract: A curved display comprises a first substrate 100 and a second substrate 200 that are disposed opposite to each other and both curved along the first direction. The first substrate includes data lines 11 and gate lines 12. The second substrate includes light transmission parts 202 and a light shielding part 203. The light shielding part includes first light shielding portions 203b extending in the first direction and second light shielding portions 203a extending in a second direction. The second light shielding portions include a central light shielding portion a5, a first end light shielding portion al disposed on one end side in the first direction, and a middle light shielding portion disposed therebetween. A width in the first direction of the middle light shielding portion is greater than or equal to that of the central light shielding portion and the first end light shielding portion.
