Plane getting pixelated.

Hey guys when placing planes side by side they are getting pix-elated.I am having 10-18 planes placed side by side. But some planes get pixelated. I am using orthographic camera.Here is the

of how does it look.Each of the following is a prefab containing plane and text.Can anyone suggest what is the problem.And another thing all has same Y coordinates but still they all are not in the same line.

Looks like either your planes or your camera aren’t/isn’t rotated to a perfect square angle (0, 90, 180, 270). First check your camera. If even one of the rotations is not the previously mentioned numbers, there’s your problem.
