The present application provides a splicing display device includes a liquid crystal display screen and an inorganic light emitting diode display screen. A color point coordinate of a color of a light emitted by the liquid crystal display screen in the CIE 1931 XYZ chromaticity diagram is in a first gamut triangle. A color point coordinate of a color of a light emitted by the inorganic light emitting diode display screen in the CIE 1931 XYZ chromaticity diagram is in a second gamut triangle. A gamut boundary of the second gamut triangle surrounds a gamut boundary of the first gamut triangle, and a difference between a NTSC color gamut corresponding to the second gamut triangle and a NTSC color gamut corresponding to the first gamut triangle is less than 30%.
