A light-emitting module includes a light guide plate and a light source unit in accordance with an embodiment. The light guide plate include an upper surface, a lower surface facing the upper surface, a plurality of side surfaces connecting the upper surface and the lower surface, and a cross-sectional surface connected to at least one of the side surfaces. The light source unit includes a substrate disposed in correspondence with the cross-sectional surface and a point light source mounted on the substrate to emit light to the cross-sectional surface. Thus, light-emitting efficiency may be enhanced and the arrangement of point light sources may be optimized, so that a required amount of emitted light may be obtained using a small number of the point light sources. In addition, uniformity of luminance and heat-radiating efficiency may also be enhanced.

A conductive bump including a plurality of protrusion members (251) and a conductive layer (252) formed on the protrusion members is disposed on a TFT substrate (200). Each of the protrusion members is disposed on an electrode pad (270y, b, 280c, b) in a pad region (292, 293) of the TFT substrate, and the conductive layer is electrically connected to the electrode pad. A non-conductive resin (600) is disposed on the conductive bump, and a driving IC (500) is thermally compressed on the conductive bump. Therefore, the electrical contact characteristic between the driving IC and the electrode pad is improved.

The input and first output terminals formed on other region than an edge portion of a base body, on which stress is concentrated, enhance a reliability of electric connection between the driver chip and a display panel.
摘要:
In an anisotropic conductive film including conductive particles, and a bump, and a packaging structure of a semiconductor chip having the anisotropic conductive film and the bump, the anisotropic conductive film includes a resin layer and the conductive particles. The anisotropic conductive film electrically connects an electrode of a substrate and the bump of a semiconductor chip. A volume ratio of the conductive particles to the resin layer is about 0.1 to about 0.12. A number of the conductive particles per m3 is about 4 millions to about 7 millions. A standard deviation of heights of the bumps is no more than about 0.25. An interval between each of the bumps and an electrode of the substrate is no more than about 1.3 μm. Therefore, the size of each of the conductive particles is optimized so that a failure probability of the open circuit is decreased.
