Greater than 95% of the cost of a TV is in the panel.
TV panels must have a near 0% defect rate and a single piece of dust during the manufacture will render the finished panel e-waste. The bigger the panel the risk of a defect goes up exponentially because the surface area for any defect becomes bigger. It follows the same issue as to why chip companies introduced chiplets, the smaller die sizes improves the yield and they can throw away less silicon.
A TV panel is basically a 50in chip, and a mobile phone display is a 6in chip.
