An anti-reflection bottom-emitting type OLED display device and a manufacturing method are provided. The anti-reflection bottom-emitting type OLED display device includes a substrate, multiple drive transistors, and a light emitting layer. The substrate is provided with a plurality of black matrixes spaced apart from each other. The drive transistors are arranged in an array on the substrate and arranged corresponding to the black matrixes respectively. The light emitting layer is disposed on the drive transistors. An opening region is arranged between each two adjacent black matrixes. The light emitting layer includes multiple light-emitting material layers arranged in an array. Each light-emitting material layer defines a display region and a non-display region. Each opening region is arranged corresponding to each display region, and each non-display region is arranged corresponding to each black matrix. Each display region coincides with each opening region between the black matrixes on the substrate.
