Claim:
1. A light emitting apparatus, comprising: a plurality of light emitting elements arranged in a matrix including rows and columns, the plurality of light emitting elements being grouped into pixel groups that each include at least a first light emitting element and a second light emitting element that are adjacent to each other in a same row, each of the plurality of light emitting elements including a first electrode and a second electrode; for each row of the plurality of light emitting elements, a first control line coupled to the second electrode of the first light emitting element of each pixel group in the row; for each row of the plurality of light emitting elements, a second control line coupled to the second electrode of the second light emitting element of each pixel group in the row; for each of the plurality of pixel groups, a driving circuit shared by the light emitting elements of the pixel group, the driving circuit including a driving transistor coupled to the first electrode of each of the light emitting elements of the pixel group; and a scanning circuitry configured to, for each of the plurality of pixel groups, time-divisionally and selectively cause a driving current to flow through the first and second light emitting elements, by: wherein the driving circuit comprises, in addition to a holding capacitor configured to retain a signal voltage of an image signal, a sub capacitor for supplementing shortage of capacitive components of the first and second light emitting elements, wherein the scanning circuitry and the driving circuit are configured to perform a mobility correction function of compensating for a dispersion in the driving transistor mobility, wherein the scanning circuitry causes the mobility correction function to be performed for the first and second light emitting elements throughout a correction period whose duration is set by the scanning circuitry in advance based upon capacitance values of the driving circuit, which include a capacitance of the holding capacitor, the capacitive components of the first and second light emitting elements, and the sub capacitor, wherein, within a period within which the mobility correction function is performed, the second potential is applied to the first and second control lines, and wherein the first and second control lines are formed in a layer different from a layer in which the driving circuit is formed.
