Abstract
A display panel and a display apparatus are provided. The display panel includes at least two sub-panels spliced with each other. A medium material is filled between two adjacent sub-panels. A lateral surface of the sub-panel in contact with the medium material is defined as a splicing surface. The splicing surface of at least one of two spliced sub-panels includes grooves. In a splicing process, the medium material may flow through the grooves, so that fluidity of medium material is improved and the bubbles is prevented in medium materials, thereby reducing the visibility of splicing seams caused by light scattering at bubbles.
