The invention provides an embedded
touch panel. Multiple touch
electrode lines are arranged in a third
metal layer of an array substrate. The touch
electrode lines on which columnar spacers stand correspondingly are overlapped touch
electrode lines, grooves are formed in the regions, corresponding to the overlapped touch electrode lines, of a flat layer of the array substrate, the overlapped touch electrode lines are correspondingly arranged in the grooves, the
standing height of the column spacers standing on the third
metal layer correspondingly is reduced, and therefore the overall box thickness of the panel is uniform. Compared with an existing improvement method, it is not needed to disconnect the touch electrode lines in the third
metal layer or reduce the number of the touch electrode lines, therefore, touch performance and pixel electric fields are not affected, only the
exposure manufacturing procedure of the flat layer needs to be slightly improved on the aspect of the manufacturing procedures, the manufacturing procedures are simple, and the production cost is low.
