Disclosed herein are an LED package module capable of lowering the price of manufacture by simply reducing the number of LED packages without decreasing the luminance, and a display device having the same. To this end, in an LED package module according to an exemplary embodiment of the present disclosure and a display device having the same, a plurality of LED packages is mounted on an LED module substrate in a matrix such that the LED packages are oriented in intersecting directions alternately in each of the longitudinal and lateral directions. Consequently, it is possible to increase price competitiveness by simply reducing the number of LED packages without degrading the display quality.
