The invention discloses a luminous unit coplanar structure of a micro light emitting diode display. The micro light emitting diode display is formed through an array which is formed by arranging multiple luminous units on a substrate; the luminous units are formed by arranging red, green and blue LED chips on a support plate; the height of at least one LED chip in the red, green and blue LED chipsincluded by the luminous units is relatively greater than that of other LED chips so that height difference can be formed; the first surface of the support plate is provided with at least one groovefor accommodating the LED chip with relatively large height; and each groove has a depth which is approximately equal to the height difference. Thus, the red, green and blue LED chips can form a coplanar state on the support plate so as to enhance the luminous uniformity of the micro light emitting diode display at different visual angles. 本发明公开了一种微发光二极管显示器的发光单元共平面结构，该微发光二极管显示器是由多个发光单元在一基板上排列形成一阵列所构成，该发光单元是由红、绿、蓝LED芯片排列设在一
