When an electrical field is applied, the crystals align perpendicular to the surface of the screen, allowing light to pass through. Therefore, for an eink display under the LCD to show through, the LCD panel would have to be switched on (and constantly drawing power) at all times. And surely would cut down hugely on the amount of reflected light reaching and bouncing back from the eink display to the outside.
