Multiplexer and method of manufacturing the same

PURPOSE: A multiplexer and a method for manufacturing the same are provided to improve the efficiency of a manufacturing process and enhance the operational reliability of the multiplexer by replacing a short-circuiting unit and a connection unit with switching elements. CONSTITUTION: A plurality of signal lines, which is arranged on a substrate(100), is expanded along a first direction and electrically insulated from each other. A plurality of address lines(300) is expanded along a first direction and a second direction, which is different from the first direction, from the upper part of the signal lines. The plurality of address lines is electrically insulated from the signal lines(200). A plurality of switching elements is located on a signal line that crosses the address lines. The plurality of switching elements selectively transmits a data signal, which passes through the signal line according to coding signal from the address lines. The plurality of signal lines is distinguished based on the combination of the coding signal.
