Abstract: A display device comprises a substrate; a driving transistor including a first active layer and a switching transistor including a second active layer, the first active layer and the second active layer being disposed on the substrate; a first gate insulating layer disposed on the first active layer of the driving transistor and the second active layer of the switching transistor; first and second gate electrodes disposed on the first gate insulating layer to overlap the first active layer of the driving transistor and the second active layer of the switching transistor, respectively; a first interlayer insulating layer disposed on the first gate electrode and the second gate electrode; and a second interlayer insulating layer disposed on the first interlayer insulating layer to overlap the first active layer without overlapping the second active layer in a plan view.

Abstract: A system and method for a vehicle charging service, includes a charging server configured to network with the plurality of chargers, receive a provisioning certificate identification (PCID) from outside, look up the received PCID in user information, allow charging of the charger connecting with the vehicle corresponding to the received PCID when the user information matching the received PCID is present, and updating the matching user information with the received PCID when the received PCID is a new PCID.

Abstract: Provided is a music providing system and apparatus for use with a music broadcasting and a music providing method using the same. The music providing system includes a communication module which receives a request signal including channel information and a request signal input time point from a music providing apparatus which receives a music broadcasting from a music broadcasting station server, provides the received music broadcasting to a user, and inputs the request signal for music which is being broadcasted on a specific channel being listened to by the user. The present invention also includes a control module which transfers the request signal to a music providing server, receives a music file which is identified by the music providing server through a broadcasting schedule of the music broadcasting station server and provides the received music file to the music providing apparatus.
