A touchscreen includes a touch drive electrode, a touch sensing electrode, a touch drive circuit, a gate drive circuit, a touch drive electrode lead, and a liquid crystal panel. The touch drive electrode extends along a first direction. The touch drive circuit is disposed in a non-display area of the touchscreen, and an extension direction of the touch drive circuit is parallel to an extension direction of the touch drive electrode. The extension direction of the touch drive circuit is the same as the extension direction of the touch drive electrode. Each touch drive electrode is connected to the touch drive circuit using a touch drive electrode lead. The touch drive electrode lead is disposed in an area in which a gate drive circuit is located. The touch drive electrode lead and the gate drive circuit are disposed in an overlapping manner and are isolated from each other.
