Abstract

A display device includes: a transformer including a core including a first surface and a protrusion protruding from the first surface along a direction which the first surface faces, wherein a cross-section of a first portion of the protrusion perpendicular to the direction which the first surface faces has a first area and a cross-section of a second portion of the protrusion between the first portion and the first surface has a second area that is larger than the first area; a first inductor sub-assembly including a first bobbin having a first opening corresponding to the first area, to be in contact with an outer circumference of a first portion of the core, and an inductor wound around the first bobbin; and a second inductor sub-assembly including a second bobbin having a second opening corresponding to the second area, to be in contact with an outer circumference of a second portion of the core, and an inductor wound around in the second bobbin.
