1. A light-emitting module, comprising:
a backlight module and a first circuit board electrically connected to the backlight module, wherein
the first circuit board comprises a first surface and at least one first electrical connection terminal on the first surface;
the backlight module comprises a second circuit board, wherein the second circuit board comprises at least one second electrical connection terminal, and the at least one first electrical connection terminal and the at least one second electrical connection terminal are electrically connected on the first surface to form an electrical connection region;
the light-emitting module further comprises a fixing adhesive film, wherein the fixing adhesive film at least covers the first surface, an overlapping region of the second circuit board and the first surface, and the electrical connection region;
the fixing adhesive film comprises a first light-transmitting region, wherein the first light-transmitting region and the electrical connection region are overlapped in a first direction, the first direction is perpendicular to a plane where the first circuit board is located; and
the light-emitting module at least comprises a first state, wherein the electrical connection region is visible through the first light-transmitting region in the first state.
