摘要： In a light emitting apparatus, all pixels are fabricated using monochrome light-emitting materials. Since the light transmittances of color filters or color conversion layers are not uniform among red (R), green (G), and blue (B), exact white color cannot be displayed. In the present invention, dots for producing these colors of light, i.e., red (R), green (G), and blue (B), are arranged parallel to writing scan lines and to erasing scan lines. The brightnesses are made uniform by controlling the emission times of the emitted colors of light. According to the brightnesses obtained after passage through the colored layer with the lowest light transmittance, the emission times of colors of light passed through the other colored layers are shortened. Thus, as the brightness differences after passage can be reduced, the light emitting apparatus can display exact white color.

摘要： The reliability of an EL element is enhanced while the increase of the electric power consumption is suppressed. It becomes possible that in a SES drive, the reverse bias is applied to the EL element driven at a constant electric current. Moreover, the application of the reverse bias is performed by varying only the counter electrode, and thus withstand voltage of TFT and the increase of the electric power consumption due to the increase of voltage of the gate signal line drive circuit, which becomes a problem when changing greatly the electric current supplying line, can be suppressed. Furthermore, the reduction of the electric power consumption can also be achieved while the enhancement of the reliability is secured by making the reverse bias smaller than the forward bias. Moreover, the increase of the number of electric sources can be also suppressed by making the potential be in common with the potential of the electric source of the source signal line drive circuit or the gate signal line drive circuit, at the time when the reverse bias is applied.
