A light emitting device includes a light source panel including light emitting units, and a printed circuit board including a light source driving circuit electrically connected to the light source panel. The light source driving circuit receives a feedback voltage from each of the light emitting units, and compares the feedback voltage with a reference voltage to output a current control signal. Each of the light emitting units includes a light emitting diode connected to a first voltage line, a switching element connected with the light emitting diode and operating in response to the current control signal, and a resistor electrically connected between a feedback node and a second voltage line. The resistor includes a conductive pattern having a predetermined width disposed on the light source panel.
