Array substrate, electronic reader and manufacturing method of array substrate

The invention discloses an array substrate, an electronic reader and a manufacturing method of the array substrate, the array substrate is used for the electronic reader, and the array substrate comprises a substrate, and a driving circuit layer, a passivation layer, a flat layer and a pixel electrode layer which are stacked on the substrate in sequence; wherein the flat layer has a first thickness at a first position and has a second thickness at other positions, and the first thickness is greater than the second thickness, so that stray capacitance generated by the pixel electrode layer and the driving circuit layer at the first position is reduced compared with that generated by the pixel electrode layer and the driving circuit layer at other positions. According to the scheme, the flat layer with the first thickness is arranged at the first position, the flat layer with the second thickness is arranged at other positions, the first thickness is larger than the second thickness, stray capacitance of the fi
