Abstract
(EN)
A pixel structure may include a base substrate (10); a first insulating island (12) on a side of the base substrate (10); a first electrode (13) on a side of the first insulating island (12) opposite from the base substrate (10); a second electrode (11) on the base substrate (10) and at a peripheral area of the first insulating island (12); an active layer (14) electrically connected to the first electrode (13) and the second electrode (11); a second insulating layer (15) on a side of the active layer (14) opposite from the base substrate (10); a gate electrode (16) on a side of the second insulating layer (15) opposite from the base substrate (10); and a third insulating layer (17) on a side of the gate electrode (16) opposite from the base substrate (10).
