According to Apple Display Analyst Ross Young, the 4th generation iPhone SE will feature a new 6.1-inch LCD display with a notch.
The design will look very similar to the current iPhones with an all screen display, but previous rumors suggest that Apple will most likely not include Face ID and will instead embed Touch ID into the power button.
It is possible that the design of the iPhone SE will most likely look like the iPhone XR but will most likely feature a smaller notch since most components like those of Face ID won't be included in the chassis.
