Semiconductor nanoparticles exhibiting band edge emission and having a short emission peak wavelength are provided. Including Ag, In, Ga, and S, the ratio of the number of Ga atoms to the total number of In and Ga atoms is 0.95 or less, and has an emission peak wavelength in a range of 500 nm to less than 590 nm. The semiconductor nanoparticles emit light with a half-value width of the emission peak of 70 nm or less and an average particle size of 10 nm or less. [Selection figure] None |
