PROBLEM TO BE SOLVED: To suppress degradation of display quality caused by fluctuations of density of electrophoretic particles filling a plurality of cells segmented by partition walls. ! SOLUTION: An electrophoretic display device includes: a device substrate 1 having a pixel electrode 12; a counter substrate 2 facing the device substrate 1; a partition wall 50 segmenting a gap between the device substrate 1 and the counter substrate 2 into a plurality of cells 55; and a dispersion medium 32 containing electrophoretic particles 33, 34, filling the plurality of cells 55. A display region V where the pixel electrode 12 is disposed includes a reference point BP or a reference line BL; the partition wall 50 includes a side wall 51a and a side wall 51b farther than the side wall 51a with respect to the reference point BP or the reference line BL; and the partition wall 50 has a portion in the side wall 51a, where a gradient of the side wall 51a with respect to the device substrate 1 is gentle compared to a g |
