Black is considered as the `absence of light', or the complete absorption of the visible spectrum, from which no light reflects.
In video projectors, the light is completely blocked from reaching the screen, creating the same effect. It appears to be black because you're usually watching it in a darkened room and in relation to the brighter areas on the screen, your mind perceives it as being black. In reality, if you were to look at the screen, you'd still see that there's no light hitting it to reflect back to your ryrs from the screen.
