Title: DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Abstract:
A display panel and a manufacturing method therefor, and a display device. The display panel comprises a plurality of display units (1), and each of the display units (1) comprises a first substrate (10) and a second substrate (20) oppositely arranged. The first substrate (10) comprises a first base substrate (101), and a first electrode (102), an electrostrictive layer (103) and a reflection groove (104) arranged thereon. The second substrate (20) comprises a second base substrate (201), and a second electrode (202) and a reflection cavity (203) arranged thereon. A support (30) is arranged between the first base substrate (101) and the second base substrate (201) to keep the distance therebetween unchanged. The reflection groove (104) has a recessed portion (1041). The reflection cavity (203) has a protruding portion (2031), and the surface of the recessed portion (1041) of the reflection groove (104) matches the surface of the protruding portion (2031) of the reflection cavity (203). The first electrode (102) and the second electrode (202) are configured to form an electric field, and the electrostrictive layer (103) can be deformed under the action of the electric fields in the direction perpendicular to the first base substrate (101), so that the recessed portion (1041) of the reflection groove (104) and the protruding portion (2031) of the reflection cavity (203) can be switched between the mode where a gap (431) is formed therebetween and the mode where the surfaces of both are closely attached.
