Presumably you drove the connection pin (the one with a snap-off leader section if its a Shimano chain) in with a chain tool, then found that pin was tight so prised it apart with a screwdriver? Just FYI the proper thing to do is flex the link until it loosens up.
The link does not seem too bent and it may run through the drivetrain and shift OK. I'd be worried about having weakened the interference fit between the bent plate and the pin.
One easy solution is to get a quick link type connecter which replaces one outer plate link. You MUST get the correct connector for the brand and speed of chain you have, SRAM, KMC, Shimano etc use slightly different links.
If you had a Shimano chain (I know you don't from comments, but this is for future readers) another solution would be to get two new connector pins, remove the bent outer plate and the two inner ones either side and splice in three new links from the bit of chain you have leftover from cutting the chain to size.
