An oligoaniline compound represented by the formula (1) can provide a charge transporting thin film which shows a suppressed coloration in the visible range. Use of this thin film makes it possible to ensure a color reproducibility of a device without lowering the color purity of an electroluminescent light or a light having passed through a color filter. wherein R1 to R10 independently represent each a hydrogen atom, a halogen, etc.; m and n independently represent each an integer of 1 or more while satisfying the condition m+n≦20; and X is a structure represented by any of the following formulae (4) to (10), etc.; wherein R21 to R36 independently represent each a hydrogen atom, a hydroxyl group, etc.; p and q represent each an integer of 1 or more while satisfying the conditions p≦20 and q≦20; and W1s independently represent each —(CR1R2)p-, —O—, —S—, etc.
