Abstract

A novel display panel that is highly convenient or reliable is provided. The display panel includes a first pixel, a second pixel, and a functional layer. The first pixel includes a first display element, and the second pixel includes a second display element. The functional layer includes a first pixel circuit and a second pixel circuit. The first display element includes a first electrode, a second electrode, and a layer containing a liquid crystal material. A first distance is provided between the first electrode and the functional layer. A second distance is provided between the second electrode and the functional layer. The first electrode and the second electrode each include a region overlapping with the layer containing a liquid crystal material. The second distance is shorter than the first distance. The second display element includes a third electrode, a fourth electrode, and the layer containing a liquid crystal material. A third distance is provided between the third electrode and the functional layer. A fourth distance is provided between the fourth electrode and the functional layer. The fourth distance is shorter than the third distance and longer than the first distance.
