Therefore, it is possible to press two keyboard keys made in the elliptical form located in the same row of the keypad at the same time, so be careful when pressing the keyboard keys.

However, the keypad layout structure of the conventional mobile communication terminal is arranged in the vertical direction in which the positions of the liquid crystal display and the keypad are up and down, and when the user inputs a letter using two hands, the mobile communication is performed only on one palm surface. As it is in contact with the rear of the terminal, it is not easy to fix the mobile communication terminal, which makes the operation of the keyboard key unnatural. Moreover, the smaller the mobile communication terminal is, the narrower the key interval between the keypads is arranged in the same row of the keypad. There is a problem in that the keyboard key operation is difficult when entering a long sentence on the screen.

The present invention is to solve the problems of the prior art, an object of the present invention is to position the liquid crystal display provided in the mobile communication terminal on the left side and the keypad on the right side when entering the characters, both palms move evenly It makes contact with the rear side of the communication terminal to facilitate the fixing of the mobile communication terminal, and even if the mobile communication terminal is downsized, by securing a space that can be further spaced apart in the horizontal portion, between the keyboard keys located in the same row It is to facilitate the operation of the keyboard keys by securing a space that can be further spaced apart.

As a technical idea for achieving the object of the present invention, the keypad keys are arranged in the longitudinal direction of the mobile communication terminal, and located on the left side of the keypad, the characters input by using the keypad length of the mobile communication terminal A liquid crystal display for displaying in a direction is provided, and an arrangement structure in which the keypad and the liquid crystal display are hinged so as to be opened and closed in a horizontal direction that is left and right is provided.
