What part to replace for my all blue screen?

My phone shut down all of a sudden. Then I turn it back on & it start to have a white band on the left side of screen with a few colourful lines. Then it slowly develop a purple cloud on left TOP, which just grow to cover almost all of my screen in about 4 hours. I tried to Google and became confused as to what part I actually need to replace? The LCD screen or the digitizer? I am not sure what digitizer is also. Please help.

The digitizer is unfortunately part of the LCD. LCD had gone bad while the glass doesn't appear to be damaged. You'll need to replace LCD + Digitizer which would include the glass.

I will edit this post on where to find them and disassembly guide when I get home. Otherwise someone else may post it instead.
