Peeling the tape and EMI shield off the display reveals the ICs controlling the 1024x768 unit:

Samsung W1235 S6TNMR1X01 Display Driver

Silicon Mitus SM4031 DA1232 SMCP043, Display PMIC

416R 8227

HDU 2YC 34

Though the markings on the back of the LCD don't turn up much information, the Samsung display driver IC reveals that Apple once again went with Samsung in its display manufacturing.

Apple has reportedly been working to move away from Samsung as a primary supplier, so it's somewhat surprising to see a Samsung LCD inside. With that said, Apple often relies on multiple suppliers for a single component, meaning there's quite likely other LCD manufacturers lurking inside other iPad Minis.
