At the moment, the fingerprint identification assembly is connected with an external circuit through a wiring; the fingerprint identification assembly is located on the color film substrate 11, and the trace and the first display electrode or the first touch electrode belong to the same conductive layer. That is to say, the first electrode layer 15 in the color film substrate can be multiplexed to form the trace of the fingerprint identification assembly, and the trace of the fingerprint identification assembly does not need to be separately prepared, so that the manufacturing process is simplified, and the manufacturing cost is reduced.

If the first electrode layer 15 only includes the first display electrode, the first electrode layer 15 is a transparent electrode (for example, an ITO electrode) and serves as a common electrode, and if the first electrode layer 15 only includes the first touch electrode, the touch electrode may be a transparent electrode (for example, an ITO electrode) or a metal mesh electrode.

If the first electrode layer 15 includes a first display electrode and a first touch electrode at the same time, at this time, the first display electrode and the first touch electrode are the same electrode, and the first display electrode and the first touch electrode can be both used as the first display electrode and the first touch electrode through time-sharing display and touch driving, and the first electrode layer 15 includes only one conductive layer, or the first electrode layer 15 includes two conductive layers, the first display electrode and the first touch electrode are located on different conductive layers, and an insulating layer is provided between the first display electrode and the first touch electrode to avoid short circuit between the first display electrode and the first touch electrode.

The trace of the fingerprint identification component is on the same layer as one conductive layer in the second electrode layer 16.

In the mode shown in fig. 6, the fingerprint identification component and the second electrode layer 16 in the array substrate 11 are taken as an example for illustration, and in other modes, the two may also be different layers, although the two are different layers in the display area, and when a patterned electrode layer is formed in the display area of the display screen, the same layer forms the routing required by the fingerprint identification component in the frame area.
