If you use standard brightfield techniques the screen really isn't visible.  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.

    * Looks to be wrong footprint
    * Suggests to use with HD44780

Maybe CRYSTALONICS CDM16116?
