Discotic liquid crystals (DLCs) are a class of liquid crystals that exhibit unique properties that make them attractive for optoelectronic applications. One of their most beneficial characteristics is their charge-carrier mobility, which is facilitated along the stacking axis. This allows for the efficient movement of electrons through the material, making it useful in the construction of electronic devices. DLCs also exhibit self-assembly, self-healing, and solubility in different organic solvents, making them versatile and easy to work with. In this mini review, we provide an overview of DLCs and their practical applications, with a focus on their charge-carrier mobility and alignment. We explore the impact of alignment on the CCM of DLCs and discuss various processing techniques used to achieve alignment, such as zone-casting, Langmuir-Blodgett deposition, solution casting, surface treatment, I.R. irradiation, zone melting, electric field impact, or usage of sacrificial sheets. Understanding and controlling the alignment of DLCs is essential for the successful application of these materials in electronic devices.
