bright spot on lcd screen

hi, today i noticed a bright spot on my lcd screen of my laptop (hp dv4 asian model (core i5 model))… .. i think it was not present before… i have bought this laptop like 5-6 months ago and i rarely use it… here are some photos of the bright spot found at the bottom left of the screen… is it a dead pixel or stuck pixel? can this be removes easily or will it disappear with time?
