The utility model relates to an anti-peeking operation reliable password input unit. A circuit board, a display screen and a button unit are installed on a base. The button unit consists of an LED (Light Emitting Diode) nixie tube and a tactile switch. The anti-peeking operation reliable password input unit is characterized in that a light barrier is arranged above the LED nixie tube corresponding to each number input button, a nonopaque bar is arranged on the light barrier in a position corresponding to each light emitting section of the LED nixie tube so that light of the light emitting section is ejected vertically from the nonopaque bar and light can just reach the eyes of a user right above through the nonopaque bar while pressed buttons cannot be observed from other angles of view, thus, achieving the anti-peeking effect. The anti-peeking operation reliable password input unit provided by the utility model further has the advantages of simple process, low cost, and convenience in application.
