    摘要: A display panel includes a backlight source, a color filter layer, and a blue filter film that are sequentially stacked. The color filter layer includes a blue pixel zone, which includes a first sub-pixel section and a second sub-pixel section. The blue filter film includes a first filtration section and a second filtration section, which are arranged opposite to the first sub-pixel section and the second sub-pixel section, respectively. The backlight source emits light that passes through the first sub-pixel section and the first filtration section to form first light, and the light emitting from the backlight source passes through the second sub-pixel section and the second filtration section to form second light. The first light has a luminous intensity that is different from a luminous intensity of the second light. A mobile terminal is also disclosed.
