Zusammenfassung:A chip-mounted board including: micro light-emitting chips arranged in a matrix pattern in a light-emitting region; and a conductive line electrically connected to the micro light-emitting chips, the light-emitting region including a first region having a first luminance, a second region having a second luminance lower than the first luminance, and a third region having a third luminance lower than the first luminance and higher than the second luminance, the luminances being values determined with the same magnitude of current supplied to the micro light-emitting chips, the third region being positioned between the first region and the second region and satisfying the following formulas (1) and (2):(1+k)/(1−k)≤63.895×tan(0.5°)×500/W+6.0525  (1)L2=k×L1  (2)wherein L1 represents the first luminance, L2 represents the second luminance, and W represents a width (unit: mm) of the third region.
