1. A liquid crystal display module, comprising:
- a lamp generating light;
a light guide panel that converts an incident light from the lamp into a surface light, said light guide panel having a first refractive index;
a low refractive index layer on the light guide panel having a second refractive index which is lower than the first refractive index, reflecting the light incident to the light guide panel on the border area;
a reflective type of liquid crystal display panel that illuminates a picture by reflecting the light coming from the low refractive index layer; and
a condensing device located between the lamp and the light guide panel, said condensing device controls the angle distribution of the incident light to the light guide panel to reduce the difference between the first refractive index and the second refractive index.

Abstract
A liquid crystal display module according to an embodiment of the present invention includes a lamp to generate light; a light guide panel to convert an incident light from the lamp into a surface light, having a first refractive index; a low refractive index layer fixed on the light guide panel, having a second refractive index, which is relatively lower than the first refractive index, so as to have the light incident to the light guide panel totally reflected on the border area with the light guide panel; and a reflective type of liquid crystal display panel to realize a picture by reflecting the light going out from the low refractive index layer.
