It's the largest reason by a gigantic margin. Economies of scale are exponential in manufacturing. Things get exponentially cheaper as you make more of them. CRTs got cheap too (relatively speaking), but the scale was smaller back then. The bulkiness and high power requirements of CRTs limited their use to a narrower set of applications, and the overall global economy was smaller. They never saw this scale. Today the number of TVs plus commercial displays plus phones plus laptops plus gaming consoles plus cars plus consumer appliances with screens is just gigantic, and they all use flat panel displays. While there are different variations on flat panels there are ultimately only a few core technologies and there's a lot of overlap in how the fabrication process works for all of them. They are all delicate sandwiches of micro-electronics and light-modifying layers and various exotic materials that block, reflect, or emit light. |

not all things.
Things that can scale are things that have a non-linear scaling production output vs input. For the LCDs (and semi-conductors), the area of the output is squared, if you increased the size of the production by a linear amount (let's say, the glass width). But the work required is not quadrupled!
Things that are linear in scaling - e.g., a burger cooked, does not scale the same way (at least, not for a McDonalds burger) - it's a one to-one, even if you tried to make it scale up by having more cooks/more machines etc. Cars, to a similar degree, but the fixed cost of a car factory/assembly line vastly out weight the lack of scaling i suppose, and so cars did get cheaper but not from the scaling manufacturing, but from cheaper components, and more automated steps etc.
