<p>The present invention relates to a liquid crystal display device for a medical machinery. The liquid crystal display device for a medical machinery includes: an LED display panel to display images; a backlight unit which includes a light source to supply light; a light guide unit which converts the light supplied from the light source into a surface light source form to guide the light to the LED display panel; a plurality of light reflection units to reduce loss of light incident to the light guide unit; a plurality of luminance improvement units to improve brightness of light which is deteriorated by passing through the light guide unit, and supplies the light from the light source to the LED display panel; and a luminance adjusting unit to uniformly adjust luminance by individual pixels corresponding to pixels constituting a screen of the LED display panel inside the backlight unit. Accordingly, the present invention separately includes a liquid crystal panel unit for adjusting luminance of an LCD formed of the same LCD panel as an LED display panel, and has luminance uniformity of a level required in the medical machinery without influencing a signal input to the LED display panel by adjusting transmittance of light with respect to individual pixels of the liquid crystal panel unit for adjusting the LCD corresponding to pixels constituting the screen of the LCD display panel in one-to-one correspondence.</p> |
