Patent abstract

An OLED substrate and a manufacturing method thereof, the OLED substrate includes a substrate, and an OLED device in a sub-pixel region on the substrate. The OLED device includes an organic layer having a non-uniform thickness. The OLED substrate further includes a transmittance adjusting layer in the sub-pixel region. The transmittance of a portion of the transmittance adjusting layer corresponding to a thicker portion of the organic layer is higher than the transmittance of a portion of the transmittance adjusting layer corresponding to a thinner portion of the organic layer. The transmittance adjusting layer is located on a light exit side of the organic layer such that light emitted from the organic layer passes through the transmittance adjusting layer when the OLED substrate is in operation.
