BACK LIGHT OF LIQUID CRYSTAL DISPLAY

摘要

PURPOSE: A back light of a liquid crystal display is provided to form a carbon nano tube film with excellent adhesion characteristic to an electrode substrate and with high density, thereby obtaining uniform luminance and extending the life span of the back light. CONSTITUTION: An upper substrate(1) used as an anode is coated with an ITO film(2), and a fluorescent layer(3) is coated on the ITO film. A conductive thin film(6) is coated on the surface of a lower substrate(7) used as a cathode, and a metal thin film(9) is formed on the conductive thin film through an electroplating or sputtering. A carbon nano tube(10) is formed on the metal thin film, and fine metal grains(4) for improving adhesion to an electrode substrate and the carbon nano tube are filled between carbon nano tubes. A spacer(5) is placed between the upper and lower substrates, and the space inbetween is vacuumed.
