So I think that some generic code that writes "Hello World" to an LCD display, is not spoon feeding
With all kinds of different LCDs available from umpteen manufacturers you can not make code to write on an LCD, It will need to be specific to the brand and model.
If you search a bit (here, Keil, Raisonance, Google)you will find several examples of 'beginner code' such as "blinky".

If you do a search on LCD here, you will find more information than you ever wanted including brand specific code snippets of all kinds.

PS:
why are you calling it a Liquid Crystal Display display
