An LCD device is disclosed. The disclosed LCD device includes: a liquid crystal display panel configured to display images; a backlight unit configured to include a light source provided for emitting light and optical sheets provided for improving optical characteristics of light which is emitted by the light source; a bottom cover with a receiving portion configured to receive the liquid crystal display panel and the backlight unit; and a heat guide member disposed on a front surface of the receiving portion of the bottom cover and configured to guide the heat generated in the light source toward the liquid crystal display panel.

Liquid crystal display device

The present invention relates to a main wavelength band of a pump light source capable of improving the pump efficiency while using 1.6 &#x3bc;m fluorescence emitted from Ho:I&#x2192;Itransition as an optical amplifier, and an assistant pump wavelength band capable of accomplishing population inversion betweenIlevel andIlevel to improve the signal gain characteristics of such amplifier. The optical amplifier using optical materials to which holmium or holmium and terbium, holmium and europium, holmium and neodymium or holmium and dysprosium, etc. are doped can be pumped using a light source that emits light of 11,200&#x2dc;11,500 cmor a light source that emits light of 6,000&#x2dc;6,500 cm.
