原文（中文）

A display panel, a preparation method of the display panel, and a display device are provided. The display panel includes an array substrate, including: a backplane and multiple display units disposed on the backplane; and an optical layer, covering a side of the backplane facing towards the display units. The optical layer includes: multiple reflective portions disposed in one one-to-one correspondence with the display units, each reflective portion surrounds a corresponding display unit and exposes an end of the corresponding display unit facing away from the backplane, and the reflective portions are spaced apart from each other. The optical layer further includes: a light-shielding portion, filled between the reflective portions. The display panel provided can reduce the screen reflectivity while improving the display brightness of the screen.
