Abstract

A foldable display device (100A) is provided with: first and second display units (100a, 100a'); and biaxial hinge device (30) which connects the first and second display units such that the first and second display units can rotate about first and second rotating axes (L1, L2). The first and second display units respectively have first and second display panels (10, 10') and first and second translucent covers (20, 20'). The first and second translucent covers respectively have: first and second flat plate portions (24, 24') having flat observer-side surfaces (24a, 24a'); and first and second curved surface portions (22, 22') having observer-side surfaces (22a, 22a') as parts of the columnar curved surfaces having the first and second center axes (C1, C2) as respective center axes. The first and second rotating axes of the biaxial hinge device accord with the first and second center axes. Thus, the foldable display device having a small image joint in a state between the opened state and the closed state is provided.

Description

Technical field [0001] The present invention relates to a display device, especially a direct-view type display device. Background technique [0002] The liquid crystal display device includes a liquid crystal display panel, a backlight device, a circuit for supplying various electric signals to the liquid crystal display panel, a power source, and a housing to house these. The 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 part, a drive circuit mounting part, etc. are provided in the frame area. Because the pixels are not arranged in the border area, the border area does not contribute to the display. Although the liquid crystal display device is narrowing the frame, in principle, it cannot be without the frame area. [0003] When a large screen is formed by arranging a plurality of display panels, the frame area of ​​the ...
