There is no gas inside it is a vacuum tube.
There is no liquid inside a plasma television. The "plasma" refers to low pressure gas contained in cells that for the image. When the gas is excited by a voltage across it, it changes state from a gas to a plasma which will pass an electric current. At no time does it become a liquid.
A plasma TV should be called a "fluorescent TV" but plasma sounds better. So they're two things inside a pixel that create colour. First step would be to run electricity through each cell and ionise a gas,which makes the gas a plasma, which emits UV light. The second part is when this UV light hits a phosphor which is coated inside the pixel which emits the colour you see.
