Check this code of interfacing this controller to a 12-bit ADC: http://www.sixca.com/micro/mcs51/adc12bit/index.html
First verify that your ADC is working well, then we will check about the LCD.

hello sir......thank u for the help....but i'm using adc0804. i'm verifying the code using keil and also i'm using proteus software.i'm having problems in giving analog input to adc in proteus. i think its not taking the value properly and converting it.

It is a hardware bug then, I guess.
Can you share your schematic?
