Abstract: Disclosed are a displaying substrate and a liquid crystal display device having the same. A pad portion formed on the displaying substrate has a plurality of via holes for exposing a pad metal layer. A width of the via hole is smaller than a diameter of a conductive particle. Where the width of the via hole is larger than the diameter of the conductive particle, a depth of the via hole is smaller than the diameter of the conductive particle. Thus, a driving failure which may occur in the pad portion is prevented while maintaining a deformation ratio of the conductive particle at about 20˜60%, thereby enhancing a connecting force between the pad portion and a circuit substrate.

Abstract: A lamp assembly for a liquid crystal display device includes a lamp tube for generating light, and electrodes each having a suitable shape for receiving end portions of the lamp tube. The lamp tube and the electrodes are combined to generate the light by applying electric power to the electrodes. The lamp assembly may include multiple lamp tubes having different brightness from each other, in which the brightness difference between the lamp tubes is compensated by uniformly diffusing the light generated from the lamp tubes.
