Abstract
An organic light diode (OLED) display panel and a manufacturing method thereof are provided. The OLED display panel includes a thin film transistor layer, a pixel defining layer, and spacers formed on a substrate. Pixel units formed in pixel regions are defined by the pixel defining layer. A thin film encapsulation layer and a color film layer are formed on the pixel units. The color film layer includes color filter layers corresponding to the pixel units, and a light shielding layer disposed at each of intervals between the color filter layers. Material of the spacers is light shielding material.
