Black horizontal lines and splotches on screen

[TypeONegative69]

I've had this laptop since 2013 or 14, I don't quite remember. Within the last 6 months, the black dots and horizontal black lines have shown up, and it seems that every few weeks, a new one is popping up. It's not completely black, because you can see some color behind it and through it. 

I've hooked an HDMI cable up to it to another monitor, and the black spots are not showing up on the other monitor. I've also open the BIOS screen but the spots appear  there.  I'm wondering if this is a problem with the pixels, or the screen, and what needs to be done to fix it. They don't really affect much, but it is really annoying when I'm trying to do my work and I can't see through the spots sometimes. They seem to be spreading, or smaller ones will pop up after a few weeks. It is never been dropped and there aren't any scratches on the screen either.
