发明名称 LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF
摘要 The present invention relates to a liquid crystal display device in which an upper frame covers the periphery of a liquid crystal display panel, and a front window is provided on the liquid crystal display panel and the upper frame. A cutout is formed in the corner portion of the upper frame, allowing the liquid crystal display panel to be exposed in the corner portion thereof. Thus, in a corner portion in which the cutout is formed in the upper frame, a side surface of the liquid crystal display panel and a side surface of the front window are directly matched for accurate positioning of the display area of the liquid crystal display panel.

主权项 1. A manufacturing method of a liquid crystal display device, wherein the liquid crystal display device includes: a liquid crystal display panel including a first substrate in which TFTs and pixel electrodes are arranged in a matrix array, a second substrate which faces the first substrate, and a liquid crystal layer which is interposed between the first substrate and the second substrate, wherein an upper polarizer is adhered to the second substrate, wherein an upper frame covers a periphery of the liquid crystal display panel, wherein a third substrate is adhered on the upper frame and the upper polarizer by an adhesive, wherein the liquid crystal display panel has a side surface, the side surface including at least one of the first and second substrates, and the upper frame has at least one cutout, and a portion of the side surface is exposed by the cutout of the upper frame, the manufacturing method comprising the steps of: applying a UV adhesive to the liquid crystal display panel or the third substrate; positioning the liquid crystal display panel and the third substrate, with reference to the side surface of the liquid crystal display panel and to a side surface of the third substrate, in the cutout of the upper frame; and adhering the third substrate to the liquid crystal display panel and the upper frame by irradiating the UV adhesive with ultraviolet light.
