Abstract

The invention discloses an array substrate, a manufacturing method of the array substrate, a display panel and a display device. The array substrate comprises multiple first thin film transistors which are arranged in a display area, wherein each first thin film transistor comprises a first active layer and the material of the first active layer includes amorphous silicon; and at least one multiplexer which is arranged in a non-display area. The multiplexer comprises multiple second thin film transistor, one input end and multiples control signal lines. The first electrode of each second thinfilm transistor is electrically connected with the input end, the second electrode of each second thin film transistor is electrically connected with different data lines in the display area, and thecontrol end of each second thin film transistor is electrically connected with different control signal lines. Each second thin film transistor comprises a second active layer, and the material of thesecond active layer includes polysilicon. The material of the second active layer includes polysilicon so that the number of leads connected with the data lines can be reduced on the basis of meetingthe signal transmission speed of the data lines and the frame can be reduced.
