The present invention provides a liquid crystal display device which can enhance quality and reliability of image display by preventing the generation of bubbles in the inside of a liquid crystal display panel and, at the same time, by suppressing leaking of light from an end of a black matrix film. In the liquid crystal display panel which sandwiches a liquid crystal layer between two glass substrates, the liquid crystal layer is surrounded by a sealing material having a predetermined width. On one glass substrate, a black matrix film and an overcoat film are arranged from one-glass-substrate side such that the black matrix film and the overcoat film overlap the sealing material. The black matrix film is, in the widthwise direction of the sealing material, formed into a planar flat black matrix film until a middle position of the sealing material from a side on which the liquid crystal layer is arranged, and is formed into a slit-shaped slit black matrix film from the middle position. Due to such a constitution, an adhesion area between the glass substrate and the overcoat film under an applied region of the sealing material is enlarged and hence, an adhesion strength is increased thus largely enhancing an adhesion strength.

The present invention provides bond pads structures between semiconductor integrated circuits and the chip package with enhanced resistance to fracture and improved reliability.

By placing multiple metal pads which are connected to the bond pad through multiple metal via, the adhesion between the bond pads and the back end dielectric stacks is enhanced.
