PURPOSE: A display device of a mobile communication terminal for partly updating pixels on a screen is provided to compare currently displayed pixel values with the next displayed pixel values, so as to selectively output the next displayed pixel values. CONSTITUTION: More than one output selector(100) connected between a controller(200) and a color LCD(Liquid Crystal Display) driver(300) cuts off outputs for pixels having a predetermined setup value among plural pixels outputted to the color LCD driver(300). The controller(200) compares plural first pixel values for pixels to be displayed in a predetermined region of the next screen with plural second pixel values for pixels displayed in the predetermined region of a current screen. If the values are identical with each other as a result of the comparison, the controller(200) outputs the predetermined setup value to the output selector(100), and if the values are not identical with each other, the controller(200) outputs the plural first pixel values to the output selector(100).
