LCDs cannot be viewed without a backlight. A line of LEDs is along the screen edge. LED light is diffused across the screen so as to light every LCD pixel.
BTW, IEEE Spectrum discussed the first LCD screens. I believe RCA was manufacturing them in the late 1970s. But RCA had become dominated by MBAs. And so the operation in Raritan NJ had to make a profit immediately to survive. Products included store advertising signs and an LCD adjustable rearview mirror (to eliminate glare from headlights).
Eventually, starved for capital, that RCA division stopped making LCD products. Many years later, the Japanese discovered another American technology stifled by business school graduates. Everyone knows who then created jobs and profits. LCD technology is that old. High tech in LCD screens was LED backlighting.
