LED display device

A display device, comprising:

• a first light-emitting module, comprising a first substrate, a plurality of first LED dies disposed on the first substrate, a first reflective layer on the first substrate, and a first light-transmissive layer covering the first substrate, the plurality of first LED dies, and the first reflective layer;
• and
• a second light-emitting module, comprising a second substrate, a plurality of second LED dies disposed on the second substrate, a second reflective layer on the second substrate, and a second light-transmissive layer covering the second substrate, the plurality of second LED dies, and the second reflective layer,
• wherein the first light-transmissive layer has a first rough uppermost surface, and the second light-transmissive layer has a second rough uppermost surface,
• wherein the first light-emitting module has a first reflectivity, the second light-emitting module has a second reflectivity, and a standard deviation between the first reflectivity and the second reflectivity is not greater than 0.5,
• wherein the first light-emitting module and the second light-emitting module have a splicing position between thereof,
• wherein the first light-transmissive layer is directly attached to the plurality of first LED dies and the first reflective layer, and the second light-transmissive layer is directly attached to the plurality of second LED dies and the second reflective layer, and
• wherein the first rough uppermost surface and the second rough uppermost surface have different roughnesses.
