1. An organic light-emitting diode (OLED) display panel, comprising:
a substrate; and
a plurality of pixels forming a pixel array on the substrate,
wherein each of the plurality of pixels comprises a subpixel group that further comprises at least three subpixels emitting light in different colors and each subpixel comprises an organic light-emitting element and a color filter structure covering the organic light-emitting element,
wherein the subpixel group comprises a first subpixel that emits light in a first color which poses the longest wavelength in the subpixel group, the first subpixel is arranged adjacent to the rest subpixels of the subpixel group,
wherein a light transmission aperture of the first subpixel is larger than a light transmission aperture of each of the subpixels of other colors of the same subpixel group, the light transmission aperture being defined by a black matrix arranged around the color filter structure, and
wherein two first subpixels of two adjacent subpixel groups are arranged side by side without a black matrix between them.
