Abstract

A method of manufacturing a display panel includes: preparing a support substrate including first and second regions spaced apart from each other and a third region between the first and second regions; forming a barrier layer in the first region on the support substrate; forming a substrate material layer located in the first region to the third region on the supporting substrate; removing a portion of the substrate material layer corresponding to the third region to form a dummy substrate in the first region and a substrate in the second region; and separating the substrate from the support substrate, in which the dummy substrate includes a plurality of protrusions protruding toward the substrate, and the substrate defines a plurality of through portions corresponding to the plurality of protrusions, in which an edge of each of the plurality of protrusions includes an uneven portion.

Description

[0001] This application claims priority to and all benefits derived from Korean Patent Application No. 10-2020-0120018 filed September 17, 2020, the contents of which are incorporated herein by reference in their entirety. technical field [0002] One or more embodiments relate to a method of manufacturing a display panel. Background technique [0003] A display device is a device for visually displaying data. A display panel provided in the display device displays images. A plurality of pixels are formed in a display area of ​​the display panel. Scan lines and data lines are formed on the display panel to be insulated from each other, and a pixel circuit including a thin film transistor and a storage capacitor corresponding to each of a plurality of pixels is included in the display panel. Various wirings, scan drivers, data drivers, controllers, etc. for transmitting electrical signals to pixel circuits in the display area may be provided in the peripheral area of ​​the ...
