The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.

A pixel structure includes a base substrate(10), an insulating island(21) on the base substrate(10), a light emitting element(50) on a side of the insulating island(21) away from the base substrate(10), an insulating layer(22) on the base substrate(10) and surrounding the insulating island(21), and the insulating layer(22) is spaced apart from the insulating island(21) by a groove(G). A reflective layer(40) on a lateral side of the insulating layer(22) surrounds a periphery of the light emitting element(50), and is configured to reflect light laterally emitted from the light emitting element(50) to exit from a light emitting surface of the pixel structure. The insulating layer(22) has a height relative to a main surface of the base substrate(10) greater than a height of the insulating island(21) relative to the main surface of the base substrate(10).


6. Drawings
a.
The figure of the drawings to be published with the abstract is Figure No.     3    
as suggested by the applicant.
as selected by this Authority, because the applicant failed to suggest a figure.
as selected by this Authority, because this figure better characterizes the invention.
