Hello Didi.
It depends on what exactly is damaged. Looking closely at your pictures it seems that you will need to replace the whole lid assembly. This includes the display, bezel, top lid. Worst case scenario is that the hinges will also need replacing, along with the display brackets. you should also test the hard drive as the shock caused could have also damaged the drive.
With regards to it being worth a repair, it depends on the price of a replacement or for the whole repair. If you do not feel comfortable ordering parts and repairing yourself then try to get a few quotes and compare for the best deal for you. Do you have any insurance covering the laptop?
Hope this helps,
Wes
