1. A light-emitting device, comprising:
a transparent substrate defined with a first surface and a second surface disposed opposite to each other;
a reflection structure disposed on and contacting the second surface of the transparent substrate, wherein the reflection structure includes a reflection layer and a circuit layer, and the reflection structure is configured to define a light-transmitting window; and
a light-emitting unit disposed corresponding to the light-transmitting window, wherein the light-emitting unit is electrically connected to the circuit layer of the reflection structure, and one optical path of the light-emitting unit passes through the light-transmitting window,
wherein the reflection layer directly contacts the second surface of the transparent substrate, and distributes along the second surface of the transparent substrate,
wherein the reflection structure further comprises an optical layer, and the optical layer is disposed at one side of the reflection layer opposing to the transparent substrate.
