Hello,
As there is written in readme.txt file (https://github.com/adafruit/Adafruit_ILI9341) that these displays use SPI to communicate, 4 or 5 pins are required to interface (RST is optional). During testing of program code, I have found that if I remove the RST pin then the screen become white.
How can I make RST pin optional. Actually, I do not want to use it during interfacing to reduce the number of pin of arduino ethernet board.
Thanks in advance.

It should simply work without the reset line.
Please post some pictures of both sides of the display, showing your soldering and wiring.
