The disclosure provides a display device and another display device. The display device includes a display panel. The display panel has a functional display area. The functional display area includes a pixel. The pixel includes a white pixel and multiple display pixels. The display pixels surround at least a part of the white pixel, and the white pixel includes a pixel electrode. The another display device includes another display panel. The another display panel has a functional display area, and the functional display area includes a pixel and a signal line. The pixel includes a white pixel and multiple display pixels. The signal line includes a branch, and the branch is electrically connected to one of the display pixels. The display device and the another display device of the disclosure is capable of reducing the problem of diffraction or having a better optical sensing effect.
