An OLED display panel, a manufacturing method therefor, a display apparatus, and an electronic product. The OLED display panel successively comprises: a first luminous layer covering at least two adjacent sub-pixels comprising a first sub-pixel; a charge barrier layer covering a second sub-pixel and a third sub-pixel; a second luminous layer covering the first sub-pixel and the second sub-pixel; and a third luminous layer covering at least two adjacent sub-pixels comprising the third sub-pixel. LUMO energy levels of a main body material of the charge barrier layer, a main luminous body material of the third luminous layer, a main luminous body material of the second luminous layer and the main luminous body material of the first luminous layer sequentially decrease, or HOMO energy levels of the main luminous body material of the first luminous layer, the main luminous body material of the second luminous layer, the main luminous body material of the third luminous layer and the main body material of the charge barrier layer sequentially decrease. The technical solutions can improve the pixel density of the OLED display panel. |
