The power supply unit <NUM> and/or the main board 19a may generate heat when operated.

A shield plate 19b may cover a portion of the main board 19a, and may be mounted on or fixed to the frame <NUM>. The shield plate 19b may prevent physical and electrical damage to the main board 19a.

A shield member <NUM> may cover the main board 19a. The shield member <NUM> may be referred to as a second shield member <NUM>, a base shield member <NUM>, a heat dissipation sheet <NUM>, or a heat distribution sheet <NUM>. The shield member <NUM> may overlap all or at least part of the main board 19a. For example, the shield member <NUM> may be a graphite sheet.

Referring to <FIG> and <FIG>, as the cover <NUM> is opened and closed from the base <NUM> with respect to the hinge <NUM> (see <FIG>), the display <NUM> may be stored or housed in the base <NUM>. The display <NUM> may be moved to an outside of the base <NUM> or be stored on the base <NUM> by the arm <NUM>. When the display <NUM> is stored on the base <NUM>, the display <NUM> and the base <NUM> may be arranged in parallel to face each other.

The side cover <NUM> may cover the side surface of the display panel <NUM>, and the back cover <NUM> may be disposed at the rear of the display panel <NUM> so as to be coupled to the side cover <NUM>. A control board 70a may be positioned between the display panel <NUM> and the back cover <NUM>. For example, the control board 70a may be a light source drive board 70a, and high heat may be generated during the operation of the control board 70a. Heat generated from the control board 70a may be discharged to the outside through the back cover <NUM>.

The main board 19a that is mounted on the frame <NUM> of the base <NUM> may be positioned between the frame <NUM> and the top <NUM>. A large amount of heat may be generated during the operation of the main board 19a, and the heat may be discharged to the outside through the top <NUM>.

The first shield member <NUM> may be positioned between the control board 90a and the back cover <NUM>. The first shield member <NUM> may be fixed or bonded to the back cover <NUM>.

The housing <NUM> in which the power supply unit <NUM> (see <FIG>) is embedded may generate high heat. The light source drive board 70a may generate high heat. When the display <NUM> is stored on the base <NUM>, the housing <NUM> embedded with the power supply unit <NUM> may not overlap the light source drive board 70a. Accordingly, heat generated from the housing <NUM> and heat generated from the light source drive board 70a can be evenly distributed in the display device <NUM>.

When the display <NUM> is stored on the base <NUM>, the light source drive board 70a may overlap at least a portion of the main board 19a. Heat generated from the light source drive board 70a and heat generated from the main board 19a may be accumulated while being emitted toward each other.

Heat generated from the light source drive board 70a may be distributed horizontally by the first shield member <NUM> to be dissipated. Heat generated from the main board 19a may be distributed horizontally by the second shield member <NUM> to be dissipated. For example, the first shield member <NUM> may partially or at least partially overlap the second shield member <NUM>. As another example, the first shield member <NUM> may be aligned so as not to overlap the second shield member <NUM>. As another example, the first shield member <NUM> may be adjacent to the second shield member <NUM> while forming a boundary. Accordingly, the heat generated from the main board 19a and the heat generated from the light source drive board 70a can be distributed without accumulation.

Thus, even when the display <NUM> is stored on the base <NUM>, heat generated by the operation of the display <NUM> can be evenly distributed and dissipated.

The moisture drained from the frame <NUM> may be drained through a first closing gap d1 formed between the frame <NUM> and the top <NUM>. The moisture discharged between the frame <NUM> and the top <NUM> may be drained through a second closing gap d2 formed between the top <NUM> and the bottom <NUM>. Finally, the moisture may be discharged to the outside of the display device through a third closing gap d3 formed between the bottom <NUM> and the outer cover <NUM>.

Referring to <FIG>, a display device includes: a display module including a display panel; an arm pivotally connected to the display module; a bottom case to which the arm is pivotally connected so as to allow the display module to be stored in the bottom case; and a top case hingedly connected to the bottom case. The bottom case may include: an outer shell that defines an accommodation space; a frame positioned in the accommodation space and coupled to the outer shell; and a top disposed opposite the outer shell with respect to the frame, the top being configured to cover the accommodation space. The top may include: an arm accommodating portion recessed toward the outer shell and configured to accommodate the arm; and a drain hole formed in a portion of the arm accommodating portion.

The arm accommodating portion may include: a pivot mount to which the arm is pivotally connected; and a cable hole formed in a lateral surface of the arm accommodating portion while being adjacent to the pivot mount. The drain hole may be positioned in a periphery of the pivot mount.

The frame may include: at least one pair of beams elongated in a longitudinal direction of the arm; and a rib intersecting the at least one pair of beams. The arm accommodating portion may be positioned between the at least one pair of beams. The rib may include a trench formed as a portion of an upper portion of the rib is cut out.

A first closing gap formed between the frame and the top; a second closing gap formed between the outer shell and the top; and a third closing gap formed between the outer shell and the top case may be provided.

The top case may include: an outer cover that defines an accommodation space; a middle frame positioned in the accommodation space and coupled to the outer cover; and an inner cover coupled to the middle frame and facing the bottom case. The middle frame may include: a horizontal plate facing the inner cover; and a side wall forming a wall for the horizontal plate. The side wall may form a first obtuse angle with the horizontal plate.

The top case may open the bottom case while forming a second obtuse angle with respect to the bottom case. The first obtuse angle may be greater than the second obtuse angle.

An edge of the outer cover of the top case may form an open gap with an edge of the outer shell of the bottom case. The open gap may be adjacent to the top case and a hinge of the bottom case.

The middle frame may further include a side curve that is connected to the side wall and depressed toward the outer cover. The side curve may be adjacent to an edge of the outer shell of the bottom case.

The display module may be configured to be stored in the bottom case or stand upright from the bottom case by a pivoting movement of the arm.

The display module may be configured to: in response to the bottom case being closed by the top case, be stored between the top and the top case while facing the top; and in response to the bottom case being opened by the top case, stand upright from the top while facing the top case.
