There's no way you can remove the actual transistor layer from the glass without destroying the display. Anyhow, it's unlikely the liquid got between those two layers.
What you CAN do, however, is remove the LCD from the backlight assembly. It's not too difficult, unless the MacBook LCD uses some new hardware setup compared to other LCDs I've taken apart in the past. There should only be a few screws that secure the display to the backlight assembly. Just be careful, take your time, and be patient - the last thing you want is to crack the LCD, because then you're totally screwed.
