摘要： PROBLEM TO BE SOLVED: To provide an organic EL display device, capable of acquiring display with no unevenness of luminance at each pixel group when an images is displayed on the two pixel groups respectively, and a driving method thereof.SOLUTION: A driver IC 12 controls lighting time of each of organic EL pixels 13 and 14 so that a product of current density (=driving current/pixel area) flowing through the organic EL pixels 13 and 14 and the light time of the organic EL pixels 13 and 14 becomes constant. Thus, even when pixel area of the organic EL pixel 13 of a dot display unit 7 is different from pixel area of the organic EL pixel 14 of a segment display unit 8, display luminance of the organic EL pixels 13 and 14 is made uniform respectively, and display with no unevenness of luminance can be acquired at the dot display unit 7 and the segment display unit 8.

摘要： PROBLEM TO BE SOLVED: To deter display light from a liquid crystal display device display unit becoming hard to see under the influence of external light in a display device for automobile which has a touch panel and the liquid crystal display unit combined. SOLUTION: An uneven part is formed on an external surface of a polarizing plate 3 of the touch panel 1 and an uneven part is formed on an external surface of a polarizing plate 6 of the liquid crystal display unit. Consequently, external light which is incident on the touch panel 1 is diffused by the uneven part of the polarizing plate 3 of the touch panel 1 and the uneven part of the polarizing plate 6 of the liquid crystal display unit. Consequently, the display light from the liquid crystal display unit 2 arranged behind the touch panel 1 can be deterred from becoming hard for an observer to see. COPYRIGHT: (C)2005,JPO&NCIPI
