What is the Enable lock screen notification in my Micromax a064

I have a Micromax Bolt A064 smartphone running on android 4.4.2. I know that KitKat have the option to enable lock screen widget in security. My phone doesn't support it. But that's not the problem. When I go to Settings->Display, I find an unknown option labeled as lock screen notification. So, my final question is what is it?. I tried to enable and disable it and see the changes but nothing changed. Also, sliding from left to right have nothing. Anyone here just know what is it. I am attaching a screenshot for that.
