Abstract

A folding type display device (100A) according to the present invention includes first and second display units (100a, 100a′) and a biaxial hinge device (30) for coupling the first and second display units such that the first and second display units are rotatable around first and second rotation axes (L1, L2). The first and second display units include first and second display panels (10, 10′) and first and second light-transmissive covers (20, 20′). The first and second light-transmissive covers include first and second flat portions (24, 24′) having flat viewer-side surfaces (24a, 24a′) and first and second curved portions (22, 22′) having viewer-side surfaces (22a, 22a′) which are parts of cylindrical curved surfaces centered around first and second central axes (C1, C2). The first and second rotation axes of the biaxial hinge device match the first and second central axes. According to the present invention, a folding type display device capable of decreasing a joint in an image in an intermediate state between an open state and a closed state.

Description

technical field [0001] The invention relates to a display device, especially a direct-view display device. Background technique [0002] A liquid crystal display device has a liquid crystal display panel, a backlight device, circuits for supplying various electrical signals to the liquid crystal display panel, a power supply, and a housing for accommodating them. A liquid crystal display panel has a display area in which a plurality of pixels are arranged and a frame area around the display area. Pixel electrodes and TFTs are provided in the display area. A sealing portion, a drive circuit mounting portion, and the like are provided in the frame area. Since pixels are not arranged in the frame area, the frame area does not contribute to display. Although liquid crystal display devices are becoming narrower in frame, in principle, there cannot be no frame area. [0003] When a large screen is formed by arranging a plurality of display panels, a seam occurs on an image bec...
