First going back to the dictionary we find the word plasma can mean the following:

1-quartz
2-serum
3-protoplasm
4-gas that have equal number of ions and electrons
The plazma we are talking about is defined in the fourth definition and it work is described as follows:

“Plasma TVs use thousands of sealed, low pressure glass chambers filled with a mixture of neon and xenon. Behind these chambers are colored phosphors, one red, one blue, and one green for each chamber. When energized, these chambers of "plasma" emit invisible UV light. The UV light strikes the red, green and blue phosphors on the back glass of the display making them produce visible light.”
