Usually a voltage is applied to rotate the light and the screen relies on polarizers to make the image dark. Theoretically I could excite the screen and at least see the pixels and considered a few ways to do that. To get the above image I used crossed polarizers and a bright light with the LCD on top of a white surface. The LCD screen is much larger than a normal die so I used my largest usable objective (2x) which has a field of view on the order of 5 mm. A better setup would be to cross polarizers and shoot through it to a camera. This was just what I had lying around and it was small enough to fit on my microscope stage.
