摘要:
The present invention provides a liquid crystal display device having an ODF (one drop-fill) type middle-sized or miniaturized liquid crystal display panel. In a liquid crystal display device which includes a liquid crystal display panel having a pair of substrates, a sealing member which is formed on a peripheral portion between the pair of substrates without a cut, and liquid crystal which is sealed in a space surrounded by the sealing member between the pair of substrates, one substrate out of the pair of substrates includes at least one line layer which is formed along a first side of one substrate, and a portion of the sealing member which is formed along the first side of one substrate is formed in a zigzag pattern such that the sealing member traverses at least one line layer plural times.

The present disclosure relates to a manufacturing method of a liquid crystal display device. In one aspect, the method may include laminating two or more multipiece boards to each other by way of a sealing material, applying surface polishing to at least one of the multipiece boards using an etchant, and separating the multipiece boards into respective liquid crystal cells by cutting. In further aspects, the sealing material may include individual sealing materials which are formed on regions of the respective liquid crystal cells, an outer peripheral sealing material which surrounds the respective individual sealing materials and forms an opening at least in a portion thereof, and a weir sealing material of a pattern in which the weir sealing material is formed inside the outer peripheral sealing material and in the vicinity of the opening.

Electroluminescence elements mounted on a substrate of an OLED display device are sealed by a protective film made of synthetic resin with chemical reaction curing in place of a sealing can. The protective film is formed such that a thickness thereof is equal to or larger than a thickness of the substrate. Alternatively, the protective film is formed by laminating a plurality of resin films which differ in one of the water absorption ratio, the elastic modulus and the hardness. With respect to the protective film which is formed of a plurality of laminated films, compared to the protective film at the electroluminescence element side, the protective film which covers the former protective film has the water absorption ratio, the elastic modulus or the hardness larger than the water absorption ratio, the elastic modulus or the hardness of the former protective film. Due to such a constitution, it is possible to reduce the thickness of the OLED display device without damaging the moisture-proof property of the electroluminescence elements.
