Abstract

The present invention provides a display device capable of suppressing light from a light source for backlight from leaking to the display area side through the inner side surface of the frame. The display device includes: a display panel including a display area; a frame for accommodating the display panel; a backlight light source arranged on the back side of the display panel; The light shielding portion is provided on the side end surface side of the display panel plane and partially protruded to include a light leakage suppression portion that suppresses the light source for the backlight.

Description

technical field [0001] The present invention relates to a display device and a portable device, and more particularly to a display device and a portable device having a display panel. Background technique [0002] A display device including a display panel is known, as disclosed in Japanese Patent No. 3322629. This publication discloses a structure of a liquid crystal display device (Liquid Crystal Display, LCD) provided with wiring. On the other hand, conventional liquid crystal display devices equipped with a display panel have a structure in which a light-shielding portion (black-mask) is provided to cover a region other than a display region such as a wiring pattern of the display panel. [0003] 29 is a perspective view showing the overall configuration of a liquid crystal display device (display device) provided with a light-shielding portion covering a wiring pattern of a display panel in a conventional example. FIG. 30 is an exploded perspective view of the convent...
