I have a GT01 Panasonic LCD which it's interface is RS-232C.
I have read that the difference between RS-232 and RS-232C is their voltage level which it's ±5 V in RS232C.
Can I use a MAX232 IC to communicate with this LCD?
I'm worried that MAX232'c Voltage level (±25 V) harms the LCD.
If not, would you please propose an IC which is capable with RS-232C?

The "C" is a 1969 Specification Revision. It does not dictate 25V but is compatible with that.
Today the Spec is Ref F to expand speed, timing and low voltage enhancements and is backwards compatible.
The standard has not changed with a threshold that is the same as TTL or 1.3V = Vbe*2 but all receivers handle a wide range of Tx bipolar voltages.
Yes.
