Active matrix substrate, touch-panel-equipped display device including same, and liquid crystal display device including same

An active matrix substrate comprising:

• a plurality of data lines;
• a plurality of pixel electrodes;
• a plurality of counter electrodes each of which is provided opposite to one of the plurality of pixel electrodes, respectively, first capacitors being formed between the plurality of counter electrodes and the plurality of pixel electrodes;
• a conductive layer provided on a side opposite to the plurality of counter electrodes with respect to the plurality of pixel electrodes;
• a first insulating layer;
• a second insulating layer;
• a third insulating layer;
• and
• a plurality of signal lines that is connected to each of the plurality of counter electrodes, and supplies a touch detection driving signal to the each of the plurality of counter electrodes, the plurality of signal lines partially overlapping with the plurality of data lines;
• wherein:
• the first insulating layer is arranged between each of the plurality of pixel electrodes and the conductive layer, and the second insulating layer is arranged between each of the plurality of pixel electrodes and a corresponding one of the plurality of counter electrodes;
• the conductive layer is arranged on the third insulating layer;
• the conductive layer includes:
• a plurality of first portions each of which is provided opposite to the plurality of pixel electrodes, respectively, and overlap with the plurality of pixel electrodes, thereby forming second capacitors therebetween;
• and
• a plurality of second portions provided between the third insulating layer and the plurality of signal lines, a first surface of each of the plurality of second portions contacts the third insulating layer and a second surface of each of the plurality of second portions contacts the plurality of signal lines;
• the plurality of first portions and the plurality of second portions of the conductive layer are positioned apart from each other;
• and
• each of the plurality of first portions electrically connects to the corresponding one of the plurality of counter electrodes via a corresponding one of a plurality of first contact holes and directly contacts the corresponding one of the plurality of counter electrodes, and each of the plurality of second portions and the corresponding one of the plurality of counter electrodes are electrically connected via a corresponding one of a plurality of second contact holes through the first insulating layer and the second insulating layer, such that the plurality of first portions and the plurality of second portions are electrically connected via the corresponding ones of the plurality of counter electrodes, the corresponding ones of the plurality of first contact holes, and the corresponding ones of the plurality of second contact holes.
