Screen black line

[apple.fan]

So i have an old but beautiful Macbook Pro mid 2010 and last week these spots appeared on the screen. A couple of days after, the black line got bigger and i’m afraid this Mac is reaching his final days. Can you identify these spots? Are these dead pixels? Any of you experienced this?
Thanks for any help you can give me.

It does appear to be dead pixels. But to make sure, you should try attaching an external monitor or TV to your MBP to see if that looks okay. If the external monitor is okay, then you know the problem is with the MBP display.
