Abstract

Display device with: display panel (12); Display Department; Non-display department; Substrate member (40), which is attached to the display panel across the adhesive layer (45), having a touch panel (44) and an operation part formed in a non-display part for input operations to the touch panel; Step part (7), which is formed at least by the side of the display panel and the side of the adhesive layer, so that a gap is generated in a part between the display panel and the substrate member; And the light source unit (50), which is at least a portion of the step in the way of overlapping the display panel is configured in the gap, to provide illumination light to the operation department so that the operation part is lit.

Description

technical field [0001] The present invention relates to display devices. Background technique [0002] In recent years, demand for thin display devices (flat panel displays) such as liquid crystal display devices has been increasing, and they have been widely used in mobile devices such as smartphones and mobile phones. [0003] For example, a liquid crystal display device includes a backlight unit as an illumination device, and a liquid crystal display panel arranged to face the backlight unit. In addition, in recent years, not only a backlight unit but also a so-called touch panel and a parallax barrier panel for three-dimensional display have been superimposed on the liquid crystal display panel to improve the functionality of the display device. [0004] Here, as disclosed in Patent Document 1, it is known that, in a display device including a display part mainly for display, a plurality of operation parts for operating the display device are provided in an area other t...
