How come when I tilt my LCD I can see the inverted colors of the image?

I have a mini LCD on a portable electronic I have. Like a video iPod. It's colored, and when I tilt the screen about 90 degrees away from my face near eye level, I can see the image in its inverted colors. Why do my eyes invert the colors of the image?|||Liquid crystal generate colors by polarizing light with molecules that can be rotated using magnetic force. It's probably because liquid crystals is refracting different colors of light at different angles.|||Remember that the light has the whole spectrum of the rainbow colors. Regarding the LCD it is inverted because the beam is inverted by the machine so that you would see the screen. In iPod's there is also a spectrum of light because it acts like a mirror reflecting the light. So it inverts the colors.
