1. An LED display device, comprising:
first and second thin film transistors on a substrate;
a first LED electrically coupled to the first thin film transistor;
a second LED electrically coupled to the second thin film transistor; and
a sub LED on the first LED, the sub LED electrically coupled to the first thin film transistor and including a reflecting layer reflecting a light toward a direction opposite to the first LED,
wherein the second LED and the sub LED are configured to emit light when a signal is applied to the first and second thin film transistors.
