Remove the battery. This is the hardest part. I tried from right side as seen in the Picture .. There are 2 flat cables on zthis side (connecting the motherboard and the lower electronics, so this might not be the best direction to start (see photos later). Try using fan (i did'nt have one) ..

The blue plastic shows the tiny screw which you need to unscrew to remove the whole upper plastic thing .. I'm not sure you need to remove that part to change the display ..
