Abstract

A liquid crystal display device which can, even in case where a vibration and an impact such as drop are exerted on a note type computer in which the liquid crystal display device is mounted, prevent a fitting portion for fixing a case body and an LCD cover from disengaging and a pawl portion of the fitting portion from being damaged, and which has fixing means whose maintenance performed by detaching the case body and the LCD cover is easy. A frame-like cushion material whose internal dimension is smaller than an external dimension of a liquid crystal display element and which is formed by using a material excellent in its elastic coefficient and having a high friction factor is mounted inside the case body 4 of the liquid crystal display device, and the liquid crystal display element is fitted into the frame.

Claims (12)

1. A liquid crystal display device comprising:

a liquid crystal display element, with a pair of opposing main surfaces and an outside edge transverse to the main surfaces at the periphery of the main surfaces, in which a liquid crystal material is interposed between two opposed insulating substrates;

a case body disposed in a back side of the liquid crystal display element and supporting the liquid crystal display element;

a LCD cover disposed in a display surface side of the liquid crystal display element, having an opening portion in a display region, and accommodating the liquid crystal display element by integrating with the case body, in which the LCD cover is fitted with the case body through a fitting portion; and

a cushion material of frame-like form mounted inside the fitting portion between the case body and the LCD cover and having an inner surface surrounding the outside edge of the liquid crystal display element and holding the liquid crystal display element by fitting it into the cushion material, in which the cushion material has an outer surface opposing to the fitting portion,

wherein the LCD cover is integrated with the case body by fitting the liquid crystal display element into the cushion material and the cushion material is constituted such that the fitting portion between the case body and the LCD cover is pressed by the fact that the liquid crystal display element is fitted into the cushion material and presses the cushion material against the fitting portion, thereby strengthening the fitting of the fitting portion between the case body and the LCD cover.

2. A liquid crystal display device comprising:

a liquid crystal display element, with a pair of opposing main surfaces and an outside edge transverse to the main surfaces at the periphery of the main surfaces, in which a liquid crystal material is interposed between two opposed insulating substrates;

a case body disposed in a back side of the liquid crystal display element and supporting the liquid crystal display element, the case body having a first surrounding portion surrounding the outside edge of the liquid crystal display element;

a LCD cover disposed in a display surface side of the liquid crystal display element, having an opening portion in a display region, and accommodating the liquid crystal display element by integrating with the case body, in which the LCD cover has a second surrounding portion surrounding the outside edge of the liquid crystal display element and is fitted with the first surrounding portion of the case body through a fitting portion; and

a cushion material of frame-like form mounted inside the fitting portion between the surrounding portions of the case body and the LCD cover and having an inner surface surrounding the outside edge of the liquid crystal display element and holding the liquid crystal display element by fitting it into the cushion material, in which the cushion material has an outer surface opposing to the fitting portion,

wherein the LCD cover is integrated with the case body by fitting the liquid crystal display element into the cushion material and the cushion material is constituted such that the fitting portion between the first surrounding portion of the case body and the second surrounding portion of the LCD cover is pressed by the fact that the liquid crystal display element is fitted into the cushion material and presses the cushion material against the fitting portion, thereby strengthening the fitting of the fitting portion between the first surrounding portion of the case body and the second surrounding portion of the LCD cover.
