If you had removed LCD from your phone before unplugging the battery you could damage the back light of LCD (chip located on MoBo/sometimes an diode bypass is enough). You should check with strong light pointed directly on your screen (connect screen THEN battery and turn it on) if anything is shown.

If you can see Apple logo/Phone background then good news - motherboard should be ok, but screen should be replaced.

Ps. Keep in mind to not throw away anything from original screen - replacements often comes w/o plastic parts or metal frame.

Ps2. ALWAYS plug out the battery as soon as you get access to it inside the phone. Always and in any reparir.
