Beschreibung
Zusammenfassung:	A light guide panel comprising a light guide plate and at least one light guide element is described. The light guide plate has a first refraction index (n1). The light guide element is buried in the light guide plate and has a second refraction index (n2) larger than the first refraction index (n1) so as to increase total reflection. Therefore, light can be efficiently transmitted through the light guide panel. Besides, this invention also provides a backlight module, which includes a light source and a light guide panel as mentioned above. The light source is disposed toward the light guide element inside the light guide plate so that light-lose is decreased and light efficiency is increased.
