I put photo fromIPhone. Could you check my problem?

in the middle of screen there are some dim and light line. i think because of main frame between track pad and key board.

During the daytime I don't recognize, but when I look at the night or wathing movie.

I went to repair shop that here is no Apple store in Korea sadly. they said it my problem like physical and personal. NOWAY.

I don't really bring this stuff. I mainly use at home.

Is there anybody have same problem? How did you handle it?

My sis will go SF soon. I know there is Apple store.

Repair shop looks avoid problem. he said many people visited because of that.
