Sorry, bur since the phone is not supposed to be serviced by the user, get it checked by visiting an Apple Authorized Service Provider or Apple Store next to your place.
But you may try a few things first:
Reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.
If this does not work, and to make sure that this is not software related, set it back to factory settings, without using any backup data afterwards. Set up the rest of the personal settings manually and test the phone.
If the screen works, restore from the latest backup. If the problem comes back, the backup data contained corrupt data, causing your issues.
If it still does not work, this is a hardware issue and the phone has to be serviced by Apple or an Apple Authorized Service Provider:
Use iTunes to restore your iOS device to factory settings - Apple Support
