The present application relates to a micro LED display device and, a method for manufacturing the same. The method includes the following steps. First, a plurality of LED chips are formed on a supplying substrate. Next, a first substrate defining a plurality of groups of printed circuits is provided. Then the supplying substrate is overlaid in an inverted manner on the first substrate in such a manner that the LED chips are aligned with and attached onto the groups of printed circuits correspondingly. After the LED chips are detached from the supplying substrate, the supplying substrate is removed. Then a sol-gel glass is filled into gaps among the LED chips. Finally a second substrate is bonded with the first substrate. The present disclosure is capable of improving the yield rate and the reliability.
