    Abstract: A beam splitter/combiner includes a first light-transmitting substrate, a first light transmission element, and a second light transmission element. The first light-transmitting substrate has a first optical surface facing incident light and a second optical surface opposite to the first optical surface. The first light transmission element is disposed on the first optical surface. The second light transmission element is disposed on the second optical surface. A first color beam incident on the first light-transmitting substrate is reflected by the first light transmission element and leaves the first light-transmitting substrate. A second color beam incident on the first light-transmitting substrate passes through the first light transmission element, is reflected by the second light transmission element, then passes through the first light transmission element, and leaves the first light-transmitting substrate.
