I doubt you'll get a specific answer for this so ;
virtually all plastic cases are both screwed together and have guides that clip the two halves together. you may have to remove stickers or hidden items that may be hiding a screw, then use a jeweler's flathead screwdriver to pry the 2 apart enough to see where the clips are located using a backlight source that lets light through cracks. Once you've located the clips inside, you'll use a very small flathead jeweler's screwdriver to push it in, so it unclips. Repeat as necessary.
When handling any lcd display, be certain not to push too hard, not to get it too hot, not to leave dust behind when you re-assemble. Also, oil that comes off your fingers can inhibit electrical connections. Have rubbing alcohol (91%+ or better) handy to clean off skin oil.
