DISPLAY DEVICE AND MOBILE TERMINAL INCLUDING THE SAME

A display device and a mobile terminal including the same are discussed. The display device may include a display panel including a first pixel region and a second pixel region; a cover glass disposed on the first surface of the display panel in the second pixel area; an optical module disposed below the second surface of the display panel to face the second pixel region, and configured to guide infrared light toward a light transmitting portion of the second pixel region; and a diffractive optical element disposed on or in at least one of the cover glass and the display panel at a position corresponding to a light transmitting portion of the second pixel area. The diffractive optical element may separate infrared light from the optical module into a plurality of spot beams. 讨论了显示装置和包括显示装置的移动终端。该显示装置可以包括：显示面板，该显示面板包括第一像素区域和第二像素区域；覆盖玻璃，该覆盖玻璃在第二像素区域中设置在显示面板的第一表面上；光学模块，该光学模块设置在显示面板的第二表面下方以面对第二像素区域，并且被配置成将红外光引导向第二像素区域的透光部分；以及衍射光学元件，该衍射光学元件在与第二像素区域的透光部分相对应的位置处设置在覆盖玻璃和显示面板中的至少一者上或覆盖玻璃和显示面板中的至少一者中。衍射光学元件可以将来自光学模块的红外
