It is unfortunately very common for people to damage either their display cables or the actual display cable connector on the logic board. I can only speculate because I cannot examine it myself, but I would be willing to bet that you accidentally damaged the connector on the logic board, which could possibly require professional soldering skills to repair. Does the connector look damaged at all? If the connector looks fine, try to examine the pins inside it. Are any of them bent or out of place? If you look at the [guide|6270|guide to remove the display|stepid=27111], iFixit warns that the display data cable and display data connector are very easy to damage, and in the comments below, other people agree.
