For example, the voltage polarities of the scanning selection signal S2n+1 in the same phase of an odd frame F2M-1 and even frame F2M (M=1, 2, 3,...) are the polarities reverse from each other and the same holds true of the scanning selection signal S2n. The scanning selection signals S2n-1 and S2n are of the voltage waveforms different from each other and the voltage polarities of the same phase are the polarities reversed from each other. The flickering to be generated at the time of writing is thereby eliminated. (n=1, 2, 3,...).

It is contrived that the width of the stripe region 10 wherein the above-mentioned P type impurity is not diffused becomes less than 5.0mum. The region 6 is reversely biased when a normal bias voltage is impressed. Therefore, current is brought into stricture efficiently to the region 10 wherein the P type impurity is not diffused, and accordingly a semiconductor laser element having the distribution of gain in a narrow region can be obtained.
