Abstract

A display panel, a display apparatus and a method for manufacturing the display panel are provided. The display panel has a first display region and an optical component region. The first display region surrounds at least a part of the optical component region. The optical component region includes a pixel region and a non-pixel region. The display panel includes a first electrode and a first light-emitting module that are located in the pixel region, and at least one second electrode and a first support member that are located in the non-pixel region. One first electrode covers the first light-emitting module along a thickness direction of the display panel. One second electrode is bridged between two adjacent first electrodes. The first support member overlaps with one of the at least one second electrode along the thickness direction of the display panel.
