Abstract

The invention discloses a display device and a manufacturing method, the display device comprises a display panel and a cover plate which are oppositely arranged, the display panel comprises a displayarea and a non-display area, the display panel comprises an array substrate, and the array substrate comprises a substrate, a first metal layer, a second metal layer and a transparent conductive layer; and the array substrate comprises a step area, the step area comprises a touch electrode and a plurality of test bonding pads, the orthographic projections of the at least two test bonding pads andthe closed pattern on the plane where the underlayer substrate is located have an overlapping area, and the position, corresponding to the overlapping area, of the touch electrode is hollowed out. The touch electrodes, the transparent conductive layer, the first metal layer or the second metal layer are arranged on the same layer; and the cover plate comprises a marking area, and the orthographicprojection of the marking area and the orthographic projection of the touch electrodes on the plane where the substrate is located are at least partially overlapped. The touch electrodes are arrangedin the step area to achieve the touch function, a touch screen does not need to be externally hung, and the manufacturing process is simple.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device and a manufacturing method. Background technique [0002] Reflective electronic tags use the principle of light reflection for simple graphic display. Graphical displays mainly involve simple numbers, patterns, and price information. In this type of label, most of the information used is displayed in a single color. The displayed information colors include blue, green and red, etc., and the background is mainly black when displayed. When the contrast between the two colors is stronger, the effect of displaying information is better. [0003] However, the reflective electronic label is generally displayed on a single page, but in actual application, there are many information to be displayed, and the single page display cannot display all of them. At this time, the page turning function is required, and the page turning function is realized by ...
