An illuminated keyswitch structure includes a base plate, a keycap, and a light-emitting die package. The keycap is movably disposed above the base plate in a vertical direction. The light-emitting die package is disposed under the keycap and includes a plurality of light-emitting dies. The plurality of light-emitting dies are monochromatic light-emitting dies. Therein, among the plurality of light-emitting dies, three light-emitting dies that are adjacently arranged in an arrangement direction perpendicular to the vertical direction emit light of three different colors. The arrangement direction is respectively parallel to along side of each of the three adjacent light-emitting dies.
