This paper describes a very light wearable display so light that you can forget that you are actually wearing it. It is a virtual image display device which consists of a prism with two total internal reflection surfaces and a holographic optical element. The sophisticated display is only 3.4 mm thick, weighs 25 grams, and has high transparency, providing comfort to wear all day long. Also, its size and weight is small enough to be put on cellular phones. Optical design and experimental results are described.
